Like Jews and Muslims, Christians believe in one God. However, Christians are unique in believe that God is a Trinity of persons: Father, Son, and Holy Spirit. Although they are three distinct persons, there is no division among them: they are perfectly united. The unity of the Trinity teaches us that although there are many differences between people, we don’t have to be divided. Instead, we can be united in love.
The moment when Jesus was baptized in the Jordan river (Matthew 4:13-17) reveals to us that Jesus Christ is the Son of God, who is exactly like His Father in all things. Jesus is not the son of a violent or fighting god, but the Son of a gentle and peaceful God. In our baptism, we have been adopted as sons and daughters of our Heavenly Father. As Jesus reveals Himself during His ministry, He also challenges us to become more like Him in our thoughts, in our words, and in our actions.
Not every person is called to marriage, but every person is called to family, because God is ultimately the Father and Mother of each one of us. While God is the source of our life, He wants each one of us to have a human father and a human mother, just as God wanted His own Son Jesus to have a human father (Joseph) and a human mother (Mary). It is important for husband and wife to remain united because, when they are strongly united, they make a good shelter for their children.
