The publishing of St Ephraem's writings is of incalculable value for the pre-tribulation theology. Now it is no more a "protestant" theory "invented" in 19th century. It is a part of the early Church teaching. Even if it was a minority at that time, now with the approaching of the real End Times it comes out providentially to enlighten our way to prepare us for a pre-tribulation rapture.
Pope Benedict reviewed St Ephraem on one of his Wednesday audiences, he mentioned others of his works.
