Catechesis Resources for YM gatherings

Hello! Drawing from my experiences in the US working with youth, we used the Didache Series published by Midwest Theological Forum for Catechesis or what they would call "Sunday school" in the US. Although it is very textbook-like, its explanations and questions proved it to be a great resource for a more learned audience. They also have online resources as well. Here is the link to the MTF website for your interest: https://www.theologicalforum.org/
