A knowledge of Christ is vital to each of us if we are to live fully as images of God and if we are ever to recover in any way from sin and its effects. We are never able to leave the question of who Jesus Christ is unanswered. “Each one of us must let himself be touched personally by the question: ‘But who do you say that I am?’ You who hear Me spoken of, answer Me. What do I really mean for you?” (Pope St. John Paul II). This question never ceases to be asked in one form or another because, for each of us, to seek the identity of Christ is to seek one’s own identity; it is to seek one’s own proper activity; it is to seek to know how to love God through our bodies and how to love others by using things for their benefit; and it is even to seek salvation. In Christ’s question and its proper answer lies the entire mystery of humanity. Consequently, those who do not correctly answer the question of Christ “Who do you say that I am?” remain in a state of confusion.
Peter, the spokesman for the Apostles, correctly answered Christ’s question when he said: “You are the Christ, the Son of the living God” (Mt 16:16). However, over the centuries since Christ, especially in the first centuries after His ascension, there were many incorrect responses to Christ’s question. One of the earliest incorrect answers was offered by Arianism, named after its founder, Arius (256-336), a priest of Alexandria in Egypt. Arianism held that Christ is only human—i.e., that Christ is only a human person, possessing a human nature. Nature (essence) signifies “what” someone is. Person signifies “who” someone is. For Arius, Christ is not God. Rather, He is only a human being, albeit a human being very close to God. However, this is impossible. If Christ were only human, He could not have satisfied God’s love rejected by Adam and Eve when they sinned. Moreover, if Christ were only human He could not have revealed God to us. Therefore, He could not have revealed who we are as images of God. Arianism was condemned by the Council of Nicaea in 325.
