I invite you, therefore, in the name of the Church, to the observance of a holy Lent, by self-examination and repentance; by prayer, fasting, and self-denial; and by reading and meditating on God’s holy Word. And, to make a right beginning of repentance, and as a mark of our mortal nature, let us now kneel before the Lord, our maker and redeemer.
-Liturgy for Ash Wednesday, The Book of Common Prayer

Finally, for your consideration this holy day, Psalm 51 Misere Mei Deus
