Hi. I’m pretty sure the man you are speaking of is Tim Staples, former Assembly of God youth pastor. He’s a great Catholic apologist.
Catholic Apologetics Academy by Patrick Madrid but I’m not sure if they offer online classes. It might be worth checking out, though.
Homeschool Connections Online. It is a website with Catholic courses for homeschoolers. Adults cannot be in the live classes but they have a recorded class subscription for $30/month. In that catalog they have apologetic classes with Father Mitch Pacwa and Gary Michuta. Gary does a series called “Defend the Faith” and it is very good. There’s a trial period of $1 for 7 days. There’s a free online course about the Protestant Revolt.
Aquinas Connections - Online Catholic Courses for Adults: you can find them on Facebook. I have no personal experience with them…yet. They are somehow affiliated with Homeschool Connections Online.
My favorite is not an online class but the Catholic Answers Radio Show. They solely exist to defend the truth of the Catholic Faith. You can do a quick search on Google for Catholic Answers Podcast. You can listen free online to the podcast by doing a search on Catholic.com. It will give you a broadcast calendar with a different topic for every day of the week. The best ones to listen to are the shows for specifically for non-Catholics. They get many calls during the show and will answer many basic questions non-Catholics have.
I do not know how intellectual you are but when I began I needed simple, concise answers…nothing too verbose. So I suggest you visit these websites:
Steve Ray at Catholicconvert.com.
Steve Martignoni Biblechristiansociety.com. He has 2 minute apologetics and free audio downloads.
