Back to School! Essentials of Catholic Theology – Introduction

Back in the Fall of 2021, I became aware of a new book by evangelical theologian, Dr. Gregg Allison, entitled, “40 Questions About Roman Catholicism” (Kregal Academic, 2021, 326 pp.). Allison, a professor at Southern Baptist Theological Seminary at Louisville, Kentucky, is one of evangelicalism’s premier experts on RC-ism. See my review of the excellent “40 Questions” here. Around the same time, I also noticed was offering a free, online course on the “Essentials of Catholic Theology,” with all seven classes taught by Allison. A student’s guide/workbook was available as well.

I was on the L3Harris fast track at the time, so I resolved to take the classes after I retired. Well, I’ve been retired for four months and now have the time. So for the next seven weeks, I’ll be taking the classes and reporting back to the WordPress blogosphere on Sundays.

Most evangelicals know very little about the RC basics. There’s a real need out there. Far too many evangelicals believe the RCC teaches a variation of the genuine Good News! Gospel of salvation by God’s grace alone, through faith alone, in Jesus Christ alone, when it actually teaches a false gospel of salvation by sacramental grace and merit.

I invite you to follow along with me each week as we examine the Essentials of Catholic Theology. In fact, I encourage you to take the classes as well. The average length is only 28 minutes. The video lessons are not available at YouTube, but you can access all seven of them free of charge (your email address is the only requirement) at Once you have your free account, just type “Gregg Allison Class” in the searchbox and it will take you right to the “Essentials of Catholic Theology” main page. The student’s guide/workbook is not essential.

Time is precious and I understand many won’t have time to take the classes, so I will be providing the lesson outlines and some brief commentary with each installment.

    1. Thanks, Michael. I’m very grateful for Dr. Allison and his teaching ministry at SBTS. He and Dr. Leonardo De Chirico of Reformanda Initiative have worked closely together in their efforts to inform evangelicals about the RCC.

    1. Thanks, Michael! Your comment was the first I heard about the extension. These sports salaries are outrageous, but the Pads had to keep Manny and keep him happy. Looking forward to the season opener.

    1. Thanks, Jimmy. I’ve gone through two lessons so far and Allison does a great job. I’m glad this resource is available, but, yes, I wish it had more exposure via YouTube.
      Hope you’re travels go smoothly today!

      1. Thanks for your blessings with the travel! Right now we are literally parked on the freeway for over an hour since there’s road construction…I got a lot more to go and wish I can drive already

      2. We eventually were able to be on the road after 2 hours; we must have really been in the middle of nowhere since I tried to google for info and there was nothing about it

  1. Wow, looks amazing. I signed up but couldn’t see the classes until I clicked on “Allison, Gregg” and his face. Then I was able to see the classes. This entire site looks really cool. Thanks so much.
