First of all God is "NOT" illogical, He at times may be a-logical which means He can go beyond logic, but He is not illogical. Secondly, the doctrine of the trinity is not an "assumption". It is the normative systematic theology of God in Christianity and is based on the fact that the Bible is explicit in telling us that there is, was and forever will be only ONE God AND the fact that the Bible identifies three (and only three ) persons as God.
The obvious question is how so? The one God of the Bible is identified by (1) His names. This means He is called God either directly or indirectly, usually both. For example, it's rather obvious God the Father is called God. The Son is identified as God by some of the Apostles including Thomas at John 20:28. The Holy Spirit is identified as God at Acts 5:3-4.
(2) His titles. (Lord, king, savior, etc) Savior at Isaiah 43:11, "I, even I, am the Lord; And there is no savior besides Me." What about Jesus? Luke 2:11, "for today in the city of David there has been born for you a Savior, who is Christ the Lord."
(3) His unique attributes or characteristics of God. (omnipresence, omnipotence, and His eternality. ) Isaiah 41:4, "i, the Lord, am the first and last, I am He." Revelation 1:8, "I am the Alpha and the Omega, says the Lord God, who is anbd who was and who is to come, the Almighty." Vs17-18, "Do not be afraid, I am the first and the last, vs18, and the living One; and I was dead, and behold I am alive forevermore, and I have the keys of death and of Hades." Also Revelation 22:12-13.
(4) His unique actions. Credited with, creation, origin of God's word, salvation of men and/or creation, etc. Isaiah 44:24, "Thus says the Lord, your Redeemer, and the one who formed you from the womb. I, the Lord, am the maker of ALL THINGS, Stretching out the heavens BY MYSELF, And spreading out the earth ALL ALONE." Genesis 1:2 regarding the Holy Spirit. "And the earth was formless and void, and darkness was over the surface of the deep; and the Spirit of God was moving over the surface of the waters."
Regarding Jesus at John 1:3, "All things came into being by Him, and apart from Him NOTHING CAME INTO BEING THAT HAS COME INTO BEING." Colossians 1:16, "For by Him all things were created, both in the heavens and on earth, visible and invisible, whether thrones or dominions or rulers or authorities--ALL THINGS HAVE BEEN CREATED BY HIM AND FOR HIM."
(5) His worship. Worshipped and/or given the honor, reverence and position due to God ALONE. I'm not talking about bowing down in "obeisance" or curtsy. Jesus said at Matthew 4:10, "You shall worship the Lord your God, and serve Him only." The Greek word for worship is "proskuneo." That same word was used at Hebrews 1:6 when referring to Jesus, "And when He again brings the firstborn into the world, He says, (the Father says), And let all the angels of God worship Him."
Please note, I am NOT saying that the Father, Son and Holy Spirit are all consistently, equally and in every mention identified as God in every place they are represented in the Bible by any combination of these 5. Nor am I saying that each person of the trinity is represented equally by ALL FIVE of these means of identifying God. Lastly, I do not believe the trinity is a REQUIREMENT for salvation. It is the RESULT of salvation, for you cannot know Jesus and somehow miss the fact that He is God. You cannot have experienced the presence of the Holy Spirit of God and somehow miss that He is God. Please read Romans 8:9-11.
