I attended a prayer vigil outside an abortion clinic yesterday. It was with some Catholics from Helping God's Precious Unborn. It was a very peaceful demonstration; we just stood outside the clinic and prayed.
We prayed the rosary and a special pro-life prayer book. The prayers in the book were beautiful and very theologically rich. A group of Evangelicals would probably have just said extempore prayers. The problem with extempore prayers is you tend to run out of words to say. You also get people who show the eloquence and people who use prayer as a sort of news bulletin to update others with information.
I very much enjoyed taking part and hope to go again. I love prayer and very much believe that prayer is powerful. It also seems a great opportunity to get to meet Catholics.
