Soli Deo gloria , or "glory to God alone", stands in opposition to the veneration or "cult" perceived by many to be present in the Roman Catholic Church of Mary the mother of Jesus, the saints, or angels. Soli Deo gloria is the teaching that all glory is to be due to God alone, since salvation is accomplished solely through His will and action — not only the gift of the all-sufficient atonement of Jesus on the cross but also the gift of faith in that atonement, created in the heart of the believer by the Holy Spirit . The reformers believed that human beings — even saints canonized by the Roman Catholic Church, the popes, and the ecclesiastical hierarchy— are not worthy of the glory that was accorded them; that is, one should not exalt such humans for their good works, but rather praise and give glory to God who is the author and sanctifier of these people and their good works. It is not clear the extent to which such inappropriate veneration is actually approved by the Roman Catholic Church and so the extent to which this Sola is one of justified opposition is unclear. The Roman Catholic's official position, for example as described in the documents of the Second Vatican Council, make it clear that God alone is deserving of glory.
