We should have a 'Baptism of Jesus Sunday'. I love my father and enjoy being a father but I'd gladly trade any mention of Father's Day for a special mention of the Baptism of Jesus, one sunday a year. A good description of the Trinity is who God is and how he saves and we see this when Jesus is being baptised, we listen in on the Father talking to Son and the Holy Spirit uniting them both in an act of baptism by a prophet (John) which signals the end of one covenant and the inauguration of another.
