According to Sundays & Seasons:
In the East three great epiphanies are celebrated on this day: the magi's adoration of the Christ child, Jesus' baptism in the Jordan River, and his first miracle, in which he changes water into wine. Epiphany celebrates Christ being made known, or made "manifest," to all nations.
The sacraments are for us the great epiphany of God's grace, in which we behold the mystery of God among us. The magi offered gifts of gold, frankincense, and myrrh. Having seen the light of Christ, we offer the gift of ourselves, our time, and our possessions -- that others may also know the epiphany of God's mercy and love.
Almighty and ever-living God, you revealed the incarnation of your Son by the brilliant shining of a star. Shine the light of your justice always in our hearts and over all lands, and accept our lives as the treasure we offer in your praise and for your service, through Jesus Christ, our Saviour and Lord, whom with you and the Holy Spirit we worship and priase, one God, now and forever. Amen
