I love the collects used for the final Sundays after the Epiphany. Because the date of Easter and thus of Ash Wednesday and Lent vary from year to year, they often go unused and unheard. But they are among the most beautiful in the Prayer Book. Easter must fall between April 22 and April 25 for all of them to be used. This year, Easter is on April 24th.
The collect for the Seventh Sunday after the Epiphany in the 1979 Prayer Book is original to the first Prayer Book of 1549, and thus (I supposed) a composition of Dr Cranmer. Before the reworking of the calendar, it was the collect for Quinquagesima, the Sunday before Lent. I love it because it extols love and does so in such an antiquated diction.
Seventh Sunday after the Epiphany
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 virtue, without which whosoever liveth is counted dead before thee. Grant this for thine only Son Jesus Christ, who liveth and reigneth with thee and the Holy Spirit, one God, now and for ever. Amen.
As far as I can find, the collect for the Eighth Sunday after the Epiphany is original to the 1979 Prayer Book. It is a beautiful treatment of anxiety and faith.
Eighth Sunday after the Epiphany
Most loving Father, who willest us to give thanks for all things, to dread nothing but the loss of thee, and to cast all our care on thee who carest for us: Preserve us from faithless fears and worldly anxieties, and grant that no clouds of this mortal life may hide from us the light of that love which is immortal, and which thou hast manifested to us in thy Son Jesus Christ our Lord; who liveth and reigneth with thee, in the unity of the Holy Spirit, one God, now and for ever. Amen.
