Epiphany means Manifestation: St Leo the Great from today's Office of Readings

Dear friends, now that we have received instruction in this revelation of God’s grace, let us celebrate with spiritual joy the day of our first harvesting, of the first calling of the Gentiles. Let us give thanks to the merciful God, who has made us worthy, in the words of the Apostle, to share the position of the saints in light, who has rescued us from the power of darkness, and brought us into the kingdom of his beloved Son. As Isaiah prophesied: the people of the Gentiles, who sat in darkness, have seen a great light, and for those who dwelt in the region of the shadow of death a light has dawned. He spoke of them to the Lord: The Gentiles, who do not know you, will invoke you, and the peoples, who knew you not, will take refuge in you.

This is the day that Abraham saw, and rejoiced to see, when he knew that the sons born of his faith would be blessed in his seed, that is, in Christ. Believing that he would be the father of the nations, he looked into the future, giving glory to God, in full awareness that God is able to do what he has promised.

This is the day that David prophesied in the psalms, when he said: All the nations that you have brought into being will come and fall down in adoration in your presence, Lord, and glorify your name. Again, the Lord has made known his salvation; in the sight of the nations he has revealed his justice.

This came to be fulfilled, as we know, from the time when the star beckoned the three wise men out of their distant country and led them to recognise and adore the King of heaven and earth. The obedience of the star calls us to imitate its humble service: to be servants, as best we can, of the grace that invites all men to find Christ.

Dear friends, you must have the same zeal to be of help to one another; then, in the kingdom of God, to which faith and good works are the way, you will shine as children of the light: through our Lord Jesus Christ, who lives and reigns with God the Father and the Holy Spirit for ever and ever. Amen.
