Our church father, Tertullian said the following about the Trinity in A.D. 216. “And at the same time the mystery of the oikonomia is safeguarded, for the unity is distributed in a Trinity. Placed in order, the three are the Father, Son, and Spirit. They are three, however, not in condition, but in degree; not in being, but in form; not in power, but in kind; of one being, however, and one condition and one power, because he is one God of whom degrees and forms and kinds are taken into account in the name of the Father, and of the Son, and of the Holy Spirit.” (ibid.) What we just read is still held to as Christians when it comes to the Trinity. There is only one God, the unity of Godhood is distributed in a Trinity. This one God is made up in the name of the Father, Son, and Holy Spirit. Although three persons, they exist in one being and one God. The Father is not the Son or the Holy Spirit, and vice versa.
This teaching of the Trinity is in accordance with what the Bible says, not man-made theology. The apostle Paul wrote, “for there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one. And there are three that bear witness in earth, the Spirit, and the water, and the blood: and these three agree in one.” (1 John 5:7,8) Many people disagree with the teaching of the Trinity, but that doesn’t mean it is false. This belief has been taught for the last two thousand years. You can see this by the quote above and in John. That is a long time in the making, and still this teaching stands strong. This, the Holy Trinity, we give reverence. As believers, we praise the Father, the Son, and the Holy Spirit, three in one. One day, everyone will give an account to God. Today is the day of salvation. Come to Jesus and be saved. The Lord is waiting for people to come to Him. Amen.
It seems to me that since the Father is Spirit, it’s easy to understand that The Father’s Spirit cane infused in both the Son and Holy Spirit. That makes them 3 in one. If God had flesh and bones, then it would be incredibly hard to understand the Trinity.
