Vatican City, Mar 1, 2018 / 05:57 am (CNA/EWTN News).- A new letter issued by the Vatican's doctrinal office has reaffirmed that Christian salvation can only come through Christ and the Church, and highlighted modern expressions of Pelagian and Gnostic thought which contradict this belief.

Signed by Archbishop Luis Ladaria SJ, prefect of the Congregation for the Doctrine of the Faith, on the Feb. 22 feast of the Chair of St. Peter, the letter is addressed to the world's bishops.
