Sorry to hear about your church building!
Coming from an Evangelical background myself, and still having very good friends who are evangelicals, I have found myself having to defend some of my Catholic beliefs to them.
And I have tried to explain these beliefs in a way that I think they can relate to.
I think the biggest obstacle is our belief in the role Mary plays in the Church. When my closest friends asked me if I prayed to Mary, I said: ‘Catholics believe that the Body of Christ is One, and that it is always One. Just as I can ask you to pray for me, Catholics believe that if you were to die, I could still ask you to pray for me.’ They paused and thought about it, and then said, ‘Well, when you explain it like that.’ Of course Protestants also believe that the Body of Christ is one, so I began with a statement that I knew they believed in too. It’s important to discuss from common ground, and it is sad when either side approaches the other with the goal of disproving the others’ faith. (not that you’d do that). So IF SOMEONE ASKS YOU, this may be an idea.
This could be a great opportunity.
