The doctrine of the Trinity is fundamental to the Christian faith and helps us realize that God exists as three distinct and consubstantial persons: the Father, the Son, and the Holy Spirit. The first defense of the doctrine of the Trinity occurred in the early 3rd century by the early church father Tertullian. He explicitly defined the Trinity as Father, Son and Holy Spirit and defended Trinitarian theology against "Praxean" heresy. The heart of the Trinity lies in the fact that although the Father, Son and Holy Spirit are three distinct persons, they share the essence of one God, creator of heaven and earth, eternal, all -powerful and holy. In essence, the three persons are one God. They are co-equal, co-eternal, and worthy of the same trust and worship as God himself. At the same time, the three people are distinguished from each other in their original relationships and in their relationships with each other. It is the Father who begets, the Son who is begotten and the Holy Spirit who proceeds. The first and most important person of the Trinity is God the Father. The Father is in his position and authority; supreme among the person of the Godhead, as is reinforced in “…but for us there is but one God, the Father, from whom all things came and for whom we live; and there is one Lord, Jesus Christ, through whom all things came, and through whom we live. » (Corinthians 8:6) The Father is the wise designer and great architect of all that has happened in Creation (Col. 1:12-13).

Get the original essay Everything in heaven and earth, from creation to ultimate eternal life in heaven and hell, is planned according to the purpose of the Father's will. The Father is the giver of every good and perfect gift. He is always infinitely wise and good in his authority. The Father is worthy of the highest because he demonstrates remarkable concern, wisdom and kindness. Jesus, the Son is the second Person of the Trinity. He is eternal and begotten of the Father. God, through the Father, sent Jesus Christ to reconcile humanity to himself. This further reinforces the point that the three Persons of the Trinity serve a different purpose. Additionally, it is interesting to recognize that although the word "trinity" is not used in the Bible, there are several examples in the Bible where a reference to the Trinity is made. For example, the verse: “And this is eternal life, that they may know you, the only true God, and Jesus Christ, whom you have sent.” » (John 17:3). This says that Jesus Christ was sent to Earth by God, the Father. This further reinforces the fact that Jesus was not God himself but was the Son, a distinct person of the Trinity, who shared the essence of a universal God. As the Gospel of John relates: “In the beginning was the Word, and the Word was with God, and the Word was God. » (John 1:1). The reference to “the word” is of great importance. The Greek word is “logos” and simply means “idea” or “purpose”. God's purpose was therefore centered in Christ and so, when "the man Christ Jesus" was born, the purpose, the word, became flesh, as we read later in John: "And the Word was made flesh , and dwelt among us, (and we have seen his glory, the glory as of the only begotten of the Father,) full of grace and truth. In the same way, the Holy Spirit, who is the third Person of the Trinity, also has a unique purpose and plays an active role in our lives. In the words of Jesus in John 14:26: “But the Advocate, the Holy Spirit, whom the Father will send in my name, will teach you all things and.
