What is the best way to start a Catholic bible study group?

God bless you!!! what a great idea. i would check with your pastor and make sure you have his blessing and then present the idea to your parish council. possibly there is a retired teacher who might enjoy this task. your local archdiocese has great resources too!! as for ideas.... Pastor Art and others like him will give you all the fuel you need for your first study.... what are the common misconceptions of non Catholics and how to combat their ignorance :)
