Why do we speak of trinity?
Matthew 28.19 : "Go, make disciples of all nations, baptizing them in the name of the Father, the Son, and the Holy Spirit ...."
The question concerning the trinity escapes the most vast and highest human intelligence. He transcribes a Latin word "Trinitatis" which means: Three in one or Tri-unity. Historically, the word "trinity", used by Tertullian at the end of the second century, formally found a place in Christian theology, only in the fourth century to refute the errors affecting the divine persons. It is the doctrine of the Christian faith that has three points: There is one God; The father ; The Son and the Holy Spirit are each God and each one is a distinct person.
Isaiah 64.8 : "Yet, O Jehovah, you are our Father: we are the clay, and it is you who have formed us, we are all the work of your hands."
The word "trinity" is not found in the Holy Scriptures, so how to interpret such a doctrine? This word was simply used to formulate this reality revealed to us by The Bible on the unity of the three Divine Persons to form one God. It is a mystery, a truth of faith inexplicable by reason, we can not fully understand it. The spiritual reality is not the same as ours.
What do the Holy Scriptures say?
1- God has revealed himself under the name of the Lord, the Almighty, the Most High, the Lord. God is also the Father of Israel because he was the one who chose and trained this people for himself. God is also called Father as having given existence to all.
Ephesians 4.5 : "There is one Lord, one faith, one baptism, one God and Father of all, who is above all, and among all, and in all."
2- In the Gospels, we see God the Son become man on earth in relation to the Father. Jesus who is the only begotten Son of the Father who has come to reveal the Father in order to give eternal life to whoever believes. The Lord is true God and eternal life.
1 John 5.20 : "We know also that the Son of God has come, and has given us understanding to know the true, and we are in the true, in his son Jesus Christ. is the true God, and eternal life."
3- In the acts of the Apostles, we see God the Holy Spirit who, after his descent on earth, works to form the Church (the elect). He is a separate person who teaches. Ananias lied to the Holy Spirit who was in the assembly, but Peter said to him, "It is not to men that you have lied, but to God."
Thus we see that God's divinely inspired Word presents the action of God through three distinct Divine Persons, while it also reveals to us that there is only one God. Through these meanings of the Three in One. We can interpret one of the many mysteries of Divine essence: The mystery of three distinct divine persons in a unit involving relationships between them which our Spirit is unable to penetrate the secret.
Matthew 22.29 : "Jesus answered them," You are wrong, because you do not understand the scriptures, nor the power of God."
-In this relationship between the Divine Persons: "the Father loves the Son" and the Son says, "I love the Father".
- The Apostle Paul speaking of marriage said this: "For this reason the man will leave his father and his mother and be united to his wife; and the two will be one flesh."
-The Bible also tells us about a diversity of members that make up one body: it is the church called the body of Christ of which we are members. And in this body, we are members of one another.
John 17.20 : "It is not for them alone that I pray, but for those who will believe in me by their word, that all may be one, as you, Father, you are in me, and as I am in you so that they too may be one in us, so that the world may believe that you sent me."
Nowhere in the Bible do we find any example of exhortation to address prayers or praises to the Holy Spirit, but the Bible teaches us that His role is different from that of the Father and the Son. It is he who leads us into the truth, and who guides us in our walk. He is in us and we are exhorted to pray, by the inspiration of the Holy Spirit to the Father Almighty in the Name of Jesus. Our prayers are as follows: through the mediation of the Son, we have access to the Father through one Spirit.
Ephesians 6.18 : "Do all kinds of prayers and supplications in the Spirit at all times, watch with perseverance, and pray for all the saints."
Biblical revelations characterize blessings, where God is revealed as Father by the Son, where the Holy Spirit is given to us as a seal of God whereby God recognizes the believer as his child, and through which we can also know God as our Father. We received: "the Spirit of adoption by which we cry Abba, Father! The Holy Spirit bears witness with our spirit that we are children of God.
John 17.4 : "I have glorified you on earth, I have finished the work that you have given me to do, and now you, Father, glorify me with yourself for the glory that I had to you before the world was."
In summary: The first person is unique in that the Father is begotten by no one and proceeds from no one; the second person is unique in that the only-begotten Son is begotten of the Father; the third person is unique in that the Holy Spirit proceeds from the Father and the Son. The people of the trinity are distinct; the person of the Father is absolutely his own, like that of the Son and that of the Holy Spirit; clearly, in the Bible, they are different. What distinguishes them is not their divine nature, but their relations.
Romans 8.9 : "He is (the Holy Spirit) the Spirit of God and of Jesus Himself."
The trinity is a representation that establishes a filial relationship: Father; Son and Holy Spirit in one God. Historically, its earliest origins stem from a survey of biblical data. It allows to assert an inevitable deduction. The trinity sums up in a therm, which God affirms in his revelation of himself. If God was not Trinitarian, he could be many things but not a God of love. For there to be love, you need an "I" that speaks to a "you".
Matthew 3.17 : "And behold, a voice uttered from heaven the words, This is my beloved Son, in whom I am well pleased."
The full revelation that is alive and justifies man in the sight of God is: faith in his only-begotten Son Jesus, "the son of his Love in whom we have redemption, the remission of sins, who is the image of God invisible, the firstborn of all creation. " (Colossians 1.13).
1 Peter 1.20 : "predestined (Jesus) before the foundation of the world, and manifested at the end of time, because of you, who through him (Jesus) believe in God, who raised him from the dead and gave him the glory, so that your faith and your hope rest on God."
God was revealed to the world through the Son, for no one has ever seen God; the only-begotten Son, who is in the bosom of the Father, is the one who made him known. One must be careful while remaining fixed on the Holy Scriptures, the only source of absolute truth.
John 9.35: "Jesus heard that they had cast him out, and when he met him, he (Jesus) said to him," Do you believe in the Son of God? "He answered," Who is he, Lord, that I may believe in him? ... You saw him, said Jesus to him, and he who speaks to you is him...."
Conclusion: God could not give a full revelation of himself, so it is the Son who came down here to reveal it to us, himself conceived by the Holy Spirit. Thus the only God is fully revealed only as Father, Son and Holy Spirit. Our prayers are raised in the same way: through the mediation of the Son, we have access to the Father by one Spirit.
Ephesians 2.18 : "For through him (Jesus) we both have access to the Father, in one Spirit."
Quote from John Nelson Darby: "The trinity is a divine mystery that we can neither probe nor explain, but that we can simply receive by faith as the revelation of God to man." And as said A servant of God: I am very much afraid of the human language on this subject, but I affirm that the only full revelation of the one true God is his revelation in the "trinity".
