In the trail of the Epiphany, the Liturgy of the Church invites us now to celebrate the Baptism of Jesus Christ. By His Baptism, when He inaugurated His public life, Our Lord appears in the line of the sinners. He who never nevertheless committed any sin will take on Him all the sins of the humanity. This act of humility, is immediately approved by His Heavenly Father who accredits His messiah’s mission : ” this one is my beloved Son: in Him I put all My Love ” (Matthieu 3, 17 -). The Holy Spirit appears then under the shape of a Dove to show us the Holy Trinity : It is a Trinitarian Feast  in the Eastern Orthodox Churches.(this manifestation will also take place at the Transfiguration)
