The Catholic Apologist
A young guy called Joseph has a YouTube channel with (currently) 38 videos defending various Catholic teachings. I’ll embed three below, but it was really hard to choose, so I’ve linked to some others as well.
To all Catholics in good standing with the Church, I hope that you learn something from these videos that will help you in your life later on. To all non-Catholics and cafeteria Catholics, please be opened to the truth and let God show you the correct path.
And the videos:
The Eucharist (Part 1 – Part 2 is here)
Debunking the arguments against Mary the Mother of God (Part 1 – Part 2 is here)
