Catholic nun, Mother Miriam, attempts to differentiate between venial and mortal sins

A few weeks ago as I was driving around town, I tuned into the local Catholic radio station and caught an encore presentation of “Mother Miriam Live,” hosted by conservative Catholic nun, Mother Miriam (aka Rosalind Moss, photo above). In this particular episode (video below), listener Marie sent in an email to the show asking what the difference was between venial and mortal sins. In Roman Catholic theology, venial (pardonable, small) sins can be expiated by attending mass. Any unforgiven venial sins will allegedly be punished/cleansed in purgatory. However, mortal (deadly, grave, major) sins supposedly can only be forgiven by a priest in the confessional. Any unforgiven mortal sins will send a person straight to hell according to Catholic theology. But where exactly is the line between venial and mortal sins? Mother Miriam states the difference is obvious. Hmm.

The Catholic apologetics website, “Catholic Answers,” attempts to help Catholics differentiate between mortal and venial sins with the “explanation” below:

“For example, deliberate hatred can be venial sin or mortal sin depending on the seriousness of the hatred. The Catechism explains, “Hatred of the neighbor is a sin when one deliberately wishes him evil. Hatred of the neighbor is a grave sin when one deliberately desires him grave harm” (CCC 2303). Another example is abusive language. “Abusive language is forbidden by the fifth commandment but would be a grave offense only as a result of circumstances or the offender’s intention” (CCC 2073).

Ach. After reading the above, a reader is no further ahead differentiating between venial and mortal sin. It’s all subjective interpretation.

Mother Miriam then referred her listeners to an article, “15 Mortal Sins Catholics are Missing in Their Confessions” written by traditionalist priest, David Nix (link far below), to demonstrate that many Catholics are unaware that they often commit mortal sins. In the one-hour broadcast, Mother Miriam attempted to get through the list, but only reviewed the first five. Below is the full list with a few comments from myself.

  • Contraception, IVF (In Vitro Fertilization), and Abortion – The use of non-abortifacient contraceptives is not sinful. The RCC-endorsed rhythm-method aka “natural family planning” hypocritically aims for the same result as artificial contraception. Catholic surveys reveal the vast majority of Catholic married couples use contraceptives in defiance of RCC teaching.
  • Masturbation and/or viewing pornography, before marriage or within marriage – God’s Word states that “everyone who looks at a woman with lustful intent has already committed adultery with her in his heart.” (Matthew 5:28). Using pornography is sinful in all circumstances (note: there are many examples of paintings with nude characters at the Vatican and at other Catholic institutions – see here). As far as masturbation within marriage goes, see my note below regarding, “In marriage, anything unnatural.”
  • Immodesty, including wearing leggings and short shorts – I’ve observed Christian women wearing skin-tight leggings/yoga pants even at church. Yes, sisters, that is sinful. It’s immodest and it’s tempting your brothers to lustfully ogle you. Whoops! Almost forgot. These days, congregants at trendy mega-churches must also endure hipster pastors trotting around in skin-tight and semi-revealing skinny jeans.
  • Before marriage, making-out or anything more passionate than that – Fornication is sinful.
  • In marriage, anything unnatural – Let the marriage bed be undefiled (Hebrews 13:4). Christian married couples don’t need Catholic celibate priests or nuns dictating to them what is and isn’t God-honoring in the bedroom. As we’re all well aware, Catholic priests have a scandalously poor track record themselves in regards to unnatural sex acts.
  • Homosexual acts – Sinful.
  • Chronic failure to catechize your kids – Catholic parents “catechize” their children with the RCC’s false gospel of salvation by sacramental grace and merit.
  • Greatly harming someone’s reputation – Gossip is sinful (1 Timothy 5:13).
  • Missing Sunday Mass without good reason and/or unnecessary work on Sunday – The vast majority of Catholics (70% – pre-COVID) don’t attend obligatory weekly mass.
  • Denying your workers a fair wage – This is subjective. What is a “fair” wage? The vast majority of people don’t control payrolls anyway.
  • Getting drunk or high – Sinful.
  • Saying the name of Jesus in vain – Sinful. Many Catholics seek to “get around” this by exclaiming, “Jesus, Mary, and Joseph!”
  • Denying the Catholic faith, including any involvement in the occult, even tarot cards or Ouija boards – This is ironic because Catholicism promotes necromancy by teaching praying to dead saints. I denied my former Catholic “faith” when I trusted in Jesus Christ as my Savior by faith alone and came out of works-righteousness Catholicism. Mother Miriam would view me as a damned apostate, but I am a child of God because of my faith in Christ Jesus while she is a lost works-religionist.
  • Skipping Friday Penance – The U.S. Catholic bishops lifted the ban on meat on non-Lenten Fridays in 1966 and substituted a mandatory “act of penance” instead. Very few Catholics comply.
  • Receiving Holy Communion with any of the above sins on your heart – EVERY Roman Catholic has sin on his/her heart when they consume the alleged consecrated Jesus wafer. Thinking that they’re without sin when they line up for the faux Jesus wafer is sanctimonious self-deceit (Luke 18:9-14).

Roman Catholics seek to justify themselves by going through a list like the one above and concluding that they don’t commit any of the sins. But God’s Word says there is NOT ONE who is righteous (Romans 3:10-12). We are not sinners because we sin, we sin because we are sinners. Such wearisome list-checkings are exercises in futility. If you don’t commit the “sins” (not all of them are sins, as I indicated) on this specific list in deed, you may commit them in thought. Every person disobeys God’s moral laws in thought, deed, and by omission every day. Catholics will strain and strain over the distinctions between venial sins and mortal sins when all such differences are arbitrary and will change depending upon which priest is consulted. Sin is sin and we are all guilty sinners deserving of God’s eternal punishment. But God loves us so much He sent His Son, Jesus Christ, to save all who trust in Him.

“20 For by works of the law no human being will be justified in his sight, since through the law comes knowledge of sin. 21 But now the righteousness of God has been manifested apart from the law, although the Law and the Prophets bear witness to it— 22 the righteousness of God through faith in Jesus Christ for all who believe.” – Romans 3:20-22

Repent of (turn from) your rebellion against God and accept Jesus Christ as your Savior by faith alone and then ask the Lord to lead you to an evangelical church in your area that teaches God’s Word without compromise.

15 Mortal Sins Catholics are Missing in Their Confessions

  1. Re: missing mass on Sundays

    And missing mass without a good reason on holy days of obligation (Christmas, All Saints day, Feast of the assumption etc) as well—mortal sin.

    So what do we have here? Romanism teaches law keeping. What does the scripture say?

    Galatians 5:1‭-‬3 ESV
    For freedom Christ has set us free; stand firm therefore, and do not submit again to a yoke of slavery. Look: I, Paul, say to you that if you accept circumcision, Christ will be of no advantage to you. I testify again to every man who accepts circumcision that he is obligated to keep the whole law.

    So can Romanists keep the whole law? The Apostle says no!

    Galatians 3:10‭-‬13 ESV
    For all who rely on works of the law are under a curse; for it is written, “Cursed be everyone who does not abide by all things written in the Book of the Law, and do them.” Now it is evident that no one is justified before God by the law, for “The righteous shall live by faith.” But the law is not of faith, rather “The one who does them shall live by them.” Christ redeemed us from the curse of the law by becoming a curse for us—for it is written, “Cursed is everyone who is hanged on a tree”—

    And for adding to the Gospel, the Apostle places Romanism under an anathema.

    Galatians 1:8‭-‬9 ESV
    But even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed. As we have said before, so now I say again: If anyone is preaching to you a gospel contrary to the one you received, let him be accursed.

    1. SB, thank you for the very relevant Scripture references! The ONLY Person Who satisfactorily kept the Law was Jesus Christ. He alone is my righteousness!


    2. Re: He alone is my righteousness

      Amen to that. “Mother” Miriam deceives herself.

      1 John 1:8‭-‬10 ESV
      If we say we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness. If we say we have not sinned, we make him a liar, and his word is not in us.

      She should learn from Bernard.

      Bernard of Clairvaux (1090-1153): I confess that I am not worthy, nor can I by my own merits obtain the kingdom of heaven. Nevertheless, I have a lawful right to claim it for two reasons, for the Lord my God has obtained it for me by the bequest of the Father and the reward of his passion, for on the one hand he has gained it himself and on the other he gives it to me. I am not ashamed, then, rightly to claim it for myself by his gift. William of Saint-Thierry, Translated by Hilary Costello, OCSO, Cistercian Fathers Series: Number Seventy-Six, The First Life of Bernard of Clairvaux, Bernard’s Sickness and Satan’s Defeat, Book 1.57, Liturgical Press, 2015, Pg 60

      Bernard of Clairvaux (1090-1153): For blessed are those who hunger and thirst after righteousness, for they shall be satisfied. But what can all our righteousness be in God’s sight? Is it not reckoned as a cloth of a menstruating woman, in the prophet’s words [Isa 64:6], and, if strictly judged, will not all our righteousness be found unrighteous and inadequate?[Dan 5:27] What then will be the case of sin when even righteousness cannot defend itself? Therefore, steadfastly proclaiming with the prophet, Do not enter into judgment with your servant,[Ps 143:2] Lord, let us in all humility return to mercy, which alone can save our souls, [Jas 1:21] and consider carefully what follows: Bernard of Clairvaux, Irene Edmonds, Wim Verbaal, Sermons for the Autumn Season, On the Feast of All Saints, Sermon 1.11. United States, Liturgical Press, 2016, Pg 140

      1. Thanks a lot for these pertinent references SB. Mother Miriam sins by believing that she obeys the Law better than others.


      2. Thanks, SB. I was vaguely aware of Rosalind’s history, but I appreciate the additional info. Her patron, conservative cardinal Raymond Burke, is one of the most outspoken critics of progressive pope Francis. It’s interesting how these traditionalist Catholics see donning 12th-century garb as a higher spirituality.


      3. Re: traditionalist

        As always, I must ask this question. Francis and Vatican 2 teach that even a good Atheist or Muslim can be saved by being good, so what’s the point of becoming a Romanist?

      4. You’re absolutely right, but a Romanist would argue that the RCC’s sacraments provide tremendous graces that are not available to other works religionists and atheists.


  2. Such a stinking mess! As are all works-oriented belief systems! A major “ugh” on this stupid list. Your follow up paragraph, beginning with, “Roman Catholics seek to justify themselves …” is excellent. I hope practicing Catholics are reading your blog. Great job, Tom.

    1. Thank you, David! These Law-keepers have an absolutely impossible task on their hands! There’s no peace, no joy, no assurance, and no salvation when a person seeks to justify themselves.

  3. Wow, this sin system is very complicated! I feel guilty just reading about it.
    Too bad for them. There’s no such manual between the Bride and the Bridegroom. My husband doesn’t need to give me a list of things that offend him, I surely know! But out of love I wouldn’t offend.
    Such bondage Tom.
    Press on brother!

    1. Thank you, Lisa Beth! Some of the things on the list are difficult to read through, but I remember very well from the nuns in grammar school that kind of oppressive scrutiny and authoritarian control even in the most personal details. Yes, a believing husband and wife need no manual because the Lord and love for each other will guide them.


  4. I have a question. Isn’t Matthew 12:31 clear that the only salvific issue is blasphemy against the Holy Spirit? Everything else Jesus died to forgive as long as we repent?

    1. Thanks, Jarilissima. The Lord cleanses us of all sin when we trust in Him as Savior, but of course we need to confess our sins as we walk with the Lord in fellowship (i.e., cleaning our feet, John 13:10), but these poor Catholics are attempting to merit their salvation via lawkeeping which is an impossible task.

      1. Yup, Cathy. I’ll never forget “trying” to march in lockstep with what the nuns taught us, but having no relationship, zero, with Jesus Christ because the genuine Gospel was never presented.


  5. Day is going well so far, taught homeschool lessons, will do a Bible study on Genesis 17 shortly after lunch. Wow, snowy and icy at ROC..its been super cold here in LA but not as cold as you guys though there’s snow in the nearby mountain. It does affect me not walking at night. So less than 10 K these days =(. Will read this after lunch!

  6. I just can’t imagine having to check a list to see whether I am on my way to the non existent purgatory or a bit closer to Heaven although reading the list tomorrow may send me closer to,the gates of hell. Absolute stupid nonsense. I listened to parts of the video. What poison she spews our covered in chocolate candy. May the Lord have mercy on her soul and bring her out of the darkness of the evil RCC system into the glorious light of the one and only Saviour, Christ Jesus.
    Thank you Tom. Keep up the good work. I pray that many deceived by this worthless religious system will read your blog .

      Yes, Rosalind/Miriam comes across as a loving “Mother,” but she teaches a “gospel” that comes straight from the depths of hell.

  7. Wow this outdo any IFB lists and I love your comments for each one. You made a good point about what is fair wage and also the irony of how RC condemning occultic while also turning around and believing in sacremental magic. Also your comment pointing back to the homoerotic Catholic mural is rather illuminating of RC hypocrisy

    1. Thanks for plowing through the priest’s list and your comments. Catholicism contradicts itself on just about every argument it makes. I’ve come across many strange things involving the RCC in the five years of doing this blog, but that homoerotic mural in an RC cathedral is one of the weirdest.

      1. That mural is the strangest. Its almost borderline conspiracy theory and then you find out its real! Grateful for your blog, I do pray and just prayed God uses your many posts to witness to Catholics
