Today is the Commemoration of the Baptism of Our Lord.

Today let us do honour to Christ's baptism and celebrate this feast in holiness. Be cleansed entirely and continue to be cleansed. Nothing gives such pleasure to God as the conversion and salvation of men, for whom his every word and every revelation exist. He wants you to become a living force for all mankind, lights shining in the world. You are to be radiant lights as you stand beside Christ, the great light, bathed in the glory of him who is the light of heaven. You are to enjoy more and more the pure and dazzling light of the Trinity, as now you have received - though not in its fullness - a ray of its splendour, proceeding from the one God, in Christ Jesus our Lord, to whom be glory and power for ever and ever. Amen.
St Gregory Nazianzen, Reading for the Second Nocturn of Matins
