The Jews understood God as Creator and Father of all that he made (Deuteronomy 32:6) and they understood the nation of Israel as God’s firstborn son (Exodus 4:22). Jesus reveals the Father in an unheard of sense. He is eternally Father by his relationship to his only Son, who, reciprocally, is Son only in relation to his Father (see Matthew 11:27). The Spirit, likewise, is inseparably one with the Father and the Son. The mission of Jesus and of the Holy Spirit are the same. That is why Jesus tells his disciples that the Spirit will reveal the glory of the Father and the Son and will speak what is true. Before his Pass-over, Jesus revealed the Holy Spirit as the “Paraclete” and Helper who will be with Jesus’ disciples to teach and guide them “into all the truth” (John 14:17,26; 16:13). In baptism we are called to share in the life of the Holy Trinity here on earth in faith and after death in eternal light.
