God the Father is a title given to God in Christianity. In mainstream trinitarian Christianity, God the Father is regarded as the first person of the Trinity, followed by the second person, God the Son Jesus Christ, and the third person, God the Holy Spirit. Since the second century, Christian creeds included affirmation of belief in "God the Father (Almighty)", primarily in his capacity as "Father and creator of the universe". However, in Christianity the concept of God as the father of Jesus Christ goes metaphysically further than the concept of God as the creator and father of all people, as indicated in the Apostles' Creed where the expression of belief in the "Father almighty, creator of heaven and earth" is immediately, but separately followed by in "Jesus Christ, his only Son, our Lord", thus expressing both senses of fatherhood. God in Christianity Patriology (Christianity) and Name of God in Christianity In much of modern Christianity, God is addressed as the Father, in part because of his active interest in human affairs on the earth, in the way that a father would take an interest in his children who are dependent on him and as a father, he will respond to humanity, his children, acting in their best interests. Many believe they can communicate with God and come closer to him through prayer – a key element of achieving communion with God. In general, the title Father (capitalized) signifies God's role as the life-giver, the authority, and powerful protector, often viewed as immense, omnipotent, omniscient, omnipresent with infinite power and charity that goes beyond human understanding. For instance, after completing his monumental work Summa Theologica, Catholic St. Thomas Aquinas concluded that he had not yet begun to understand 'God the Father'. Although the term "Father" implies masculine characteristics, God is usually defined as having the form of a spirit without any human biological gender, e.g. the Catechism of the Catholic Church No. 239 specifically states that "God is neither man nor woman: he is God".
