The fascinating thing is that there is no record of St. Peter, St. Paul, St. John, St. James or any of the original Apostles praying like this...or those Christians in the earliest centuries of the Church. Nor is there any instruction at all...amidst all the detailed instructions by Paul, Peter, John et al., in their letters to the first Christians...that they should seek intercession of saints who have died at all....NOT ONE IOTA.
Clearly—according to the direct historic record of the Apostles, the New Testament, that was not a part of Aspotolic prayer and practice.
St. Mary herself—as virtuous and blessed woman she surely is—is never even mentioned in the Bible after the 2nd Chapter of Acts.
If praying to saints is such an essential, important part of the Christian life, I wonder why Paul, Peter, John, James etc. forgot to mention it?
Perhaps they forgot to mention it for the same reason they forgot to mention sola scriptura.
