23 Therefore, Venerable Brothers, since We rejoice at this increase of honor and glory for our holy Doctor, at the same time We trust that he will be an ever present and eager intercessor for the entire Christian family in these difficult times. May this also be a new testimony to the Eastern Catholics of the special care and interest which the Roman Pontiffs extend to those separated churches. We desire, just as our predecessors did, that their legitimate liturgical customs and canonical prescriptions always remain in integral safety. Would that by the grace of God and the aid of St. Ephrem those obstacles might collapse which separate so large a part of the Christian flock from the mystical rock upon which Christ founded his Church. May that happy day come as soon as possible, on which the words of Evangelical truth will be like "goads and nails firmly fixed" in all minds, words "which are given through authoritative deliberation by one shepherd."
