And, to repeat, also called Shrove Sunday or Dominica ingressus ieiunii, or as the old English bard would've written, if he'd thought of it, penance is ycumen in. And so it is with Ash Wednesday just around the corner.
The epistle for today in the traditional rite is the charity epistle, 1 Corinthians 13:1-13. The lovely old prayer book collect riffs on St Paul's text nicely:
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. Amen.
And an Old English sermon for Quinquagesima.
'Now a pure and holy time draws near, in which we should atone for our neglect. Every Christian, therefore, should come to his confession and confess his hidden sins, and amend according to the guidance of his teacher; and let everyone encourage each other to good by good example, so that all people may say of us what was said of the blind man when his eyes were enlightened: that is, All people who saw that miracle praised God, who lives and reigns forever without end. Amen.'
The rest is here in Old English and in Dr Parker's rather more modern version.
