For those of us (like me) who grew up in churches with no official formal liturgy, the term “collect” is likely unfamiliar. It simply means a general prayer, usually short, to be said by all the people together. The Book of Common Prayer has a number of very beautiful and powerful ones. Here is the 1662 ed.’s collect for Christmas Day:
ALMIGHTY God, who hast given us thy only-begotten Son to take our nature upon him, and as at this time to be born of a pure Virgin; Grant that we being regenerate, and made thy children by adoption and grace, may daily be renewed by thy Holy Spirit; through the same our Lord Jesus Christ, who liveth and reigneth with thee and the same Spirit, ever one God, world without end. Amen.
