The Book of Divine Worship, that Catholic liturgical text drawing on Anglican sources, and allowed for use by those under the Pastoral Provision for former Anglicans in the United States, includes verbatim - as the Collect for the 7th Sunday after Epiphany - the BCP Collect for Quinquagesima. As it has been baptized, so to speak, or at the least been received into full communion, I have no hesitation in quoting what is a most appropriate prayer, given the Quinquagesima Epistle of I Corinthians xiii:
O Lord, who hast taught us that all our doings without charity are nothing worth: Send thy Holy Ghost and pour into our hearts that most excellent gift of charity, the very bond of peace and of all virtues, without which whosoever liveth is counted dead before thee. Grant this for thine only Son Jesus Christ's sake, who liveth and reigneth with thee and the same Holy Ghost, one God, now and for ever. Amen.
