Having come from a Baptist background, I can truly understand what they’re doing, believe it or not. One of the beautiful things about many protestants is their firey desire for evangelism. I wish I saw that more in the catholic faith. And, you are their primary target because Baptists are taught untruths about the catholic faith: that we worship Mary, that we worship Saints, etc. They just don’t understand.
My advice would be to hop over to the library for religious books. They’re free and plentiful. Cathlicism for Dummies and Why do Cathlics do That are great resources to use when talking to protestants who don’t truly understand the church.
Think of this as an opportunity to renew your faith and show others the beautiful teachings of the Catholic Church. Maybe you’ll even show a few the way to mass, just to “visit.”
Good luck and God bless,
