The London Baptist Confession of 1689 and the Westminster Confession both identify the office of Pope, within the Roman Catholic Church, as antichrist. Many modern evangelicals have lost sight of the reason for The Reformation and think Vatican II brought Rome closer to Protestant soteriology. This is a sadly mistaken conclusion, as Rome has never refuted The Council Of Trent, which proclaims damnation on all who hold to salvation by grace alone by faith alone in Christ alone. To this day, Rome proclaims an infused grace from their false Christ that empowers the Catholic to work his spiritual birth by his own efforts.
Below is a snapshot of the Preface to a 50 page booklet by J.A. Wylie wherein he documents the biblical case that proves the perspective in the two confessions noted above. The complete booklet can be found here. May the blood-bought saints of the living God stand firm on His Word, for the glory of the Lord Jesus.
