When I started believe in God, I asked this question so many times, "what is 'Trinity'?", "what's that mean?"
I found the answer now! Thank God. I must share to you guys
The saying of the “triune God” was established in the Council of Nicaea in AD 300s. At that time, the religionists from different countries argued fiercely about God’s unicity and multiplicity. Eventually, according to man’s notion, imagination, reasoning and logic, the saying of the “triune God” was established. From then on, people thought that there is God the Father in Heaven except the Lord Jesus.
First we should know cleanly that such a saying was not spoken by God. The prophets and apostles didn’t say that, much less did the Holy Spirit ever reveal that. If there were such a saying, it must have been recorded in the Bible. It was completely concluded by corrupt mankind. Therefore, such a saying of the “Triune God” was from man’s mouth and was completely man’s will.
We can search the Bible. In the Old Testament Age of the Law, there wasn’t such a saying of the “trinity” at all. Only after the Lord Jesus was incarnated and came to the earth did the saying of “Father and Son” come into being.
It is recorded in John, Philip didn’t know God. He thought that the Lord Jesus had a God the Father in heaven. So he said to the Lord Jesus, “ Lord, show us the Father…” The Lord Jesus corrected his mistake. The Lord said, “
he that has seen me has seen the Father…” The Lord also said, “
I am in the Father, and the Father in me …” The Father is the Son and the Son is the Father, “Father and Son” are one and are one Spirit. The Lord Jesus clearly tells us that he and the Father are one.
Someone said that the Father and the Son. They are one being, but their Persons are different. Didn’t Jesus call the God in heaven Father in his prayers?
.
God’s word explains it very clearly. At that time when Jesus prayed, he called God’s Spirit in heaven Father in the position of a created being, that is, a man. But it doesn’t prove that Jesus is the Son of God’s Spirit in heaven. Before the Lord Jesus went to the cross, he was only the Son of man and the Christ, but was not a glorious body. So, the Lord Jesus called the God in heaven Father in the position of a created being, that is the flesh called the Spirit Father. It shows the Lord Jesus’ humbleness and obedience.
We can see that, there is only one God. When God is incarnated, he has the substance of divinity. After the flesh finishes his work and returns to the spiritual realm, he has God’s original identity. Jesus incarnate is the flesh God’s Spirit is realized in, and his substance is still Spirit. So, there is only God. Just because God is incarnated, there such a saying of “Father” and “Son”. However, it only means that the incarnated God calls the Father in the position of a created being. Anyhow, the saying of “Father and Son” is only applicable to the years when Jesus was incarnated. After Jesus left, there no longer such a saying of “Father and Son.” Therefore, we shouldn’t regard God as a “Triune God” because of the saying of “Father and Son.” This is untenable.
God has never said that he is triune. When Jesus said, “ baptizing then in the name of the Father, and of the Son, and of the Holy Ghost,” it means that people could be baptized in the name of the Father, in the name of the Holy Spirit, or in the name of the Son. At that time, many people had grave doubts about Jesus. If they had been certain that Jesus was the incarnated God, they could have been baptized in Jesus’ name. This is because Jesus is the Father, and the Father and the Son are one.
