Primarily there is an OPTION to pray to the Capital Letter Saints to intercede for us with God if we so choose. I don't know about this praying to get the dead out of purgatory. It was explained to me that if we can ask someone on earth to pray for us, we can also ask someone in Heaven to pray for us. The only difference between the Cap S Saints and all the other saints of God are that we can be sure the Cap S Saints are there, we don't really know with the rest. I don't know that the Anglican church is so much better than the Episcopal Church other than it hasn't gone so far over the edge. I'm glad you're happy in your decision. I hope you're not just "playing" church like the piskies are, though many of them would desperately like it to be otherwise, have even convinced themselves it is otherwise.
"I don't know about this praying to get the dead out of purgatory."
That may be a Hispanic thing (my chief exposure to RC).
No, we are not "playing church," we're serious:
