OK passionate Catholics, lets tell the world why we are Catholics and chose to stick with it. Reasons should be SOLID enough to hit it right through the head!
Let me start:**
 It’s the ONLY church instituted by Christ, the rest are by mere humans
 It’s THE universal church, the singular body of Christ! without any pieces(denominations)
processing more, just thinking of putting it in a very strong and practical way. (**150 Reasons to be Catholic ** is a great resource, but we can have a practical, right-out-of-heart version alongside to it)
