Firstly, you only know what’s in the Bible because it was decreed in a 4th century council, susan.
(And you didn’t answer the question I posed to you pages back: if the Church is fallible, how can you know that she got it right regarding the 27 book canon of the NT?)
The Scriptures were written in the 1st century by the Apostles and those who were close to their ministry. Scripture was Scripture as soon as it was written. A few fallible humans may have been confused about certain texts, but in general the New Testament was immediately recognized.
1 Timothy 5:18 For Scripture says, “Do not muzzle an ox while it is treading out the grain,”[a] and “The worker deserves his wages.”** **

a.1 Timothy 5:18 Deut. 25:4
b.1 Timothy 5:18
Luke 10:7
2 Peter 3:15 Bear in mind that our Lord’s patience means salvation, just as our dear brother Paul also wrote you with the wisdom that God gave him. 16 He writes the same way in all his letters, speaking in them of these matters. His letters contain some things that are hard to understand, which ignorant and unstable people distort, as they do the other Scriptures, to their own destruction.
Clement’s Letter to the Corinthians (ca. 95AD)
Chapter 47
“Take up the epistle of the blessed Apostle Paul. What did he write to you at the time when the gospel first began to be preached? Truly, under the inspiration of the Spirit, he wrote to you concerning himself, and Cephas, and Apollos, because even then parties had been formed among you.”

So Scripture was known to be inspired Scripture long before a council ever occurred. I believe that the right books were listed 300 years later at the councils. Being right and being infallible are 2 different things.
Secondly, there is NO WAY that anyone can read the Bible and discern "God is three consubstantial persons—the Father, the Son (Jesus Christ), and the Holy Spirit— as “one God in three Divine Persons”.
You read the Bible with the lens given to you by Sacred Tradition, and that’s how you can say that the Trinity is found in the Bible.
Jehovah’s Witnesses are correct when they ask: if you were raised on a desert island and someone left a Bible there, would you determine that God is 3 Persons in 1 God after reading it from cover to cover?
No. No one would.
There is one God:
Isaiah 44:8 Do not tremble, do not be afraid.
Did I not proclaim this and foretell it long ago?
You are my witnesses. Is there any God besides me?
No, there is no other Rock; I know not one.”
Isaiah 45:5 I am the Lord, and there is no other;
apart from me there is no God.
I will strengthen you,
though you have not acknowledged me,
Isaiah 45:22 “Turn to me and be saved,
all you ends of the earth;
for I am God, and there is no other.
John 17:3 Now this is eternal life: that they know you, the only true God, and Jesus Christ, whom you have sent.
1 Corinthians 8:5 For even if there are so-called gods, whether in heaven or on earth (as indeed there are many “gods” and many “lords”), 6 yet for us there is but one God, the Father, from whom all things came and for whom we live; and there is but one Lord, Jesus Christ, through whom all things came and through whom we live.
Jesus is God:
John 1:1 In the beginning was the Word, and the Word was with God, and the Word was God.
Colossians 2:9 For in Christ all the fullness of the Deity lives in bodily form,
John 8:58 “Very truly I tell you,” Jesus answered, “before Abraham was born, I am!” 59 At this, they picked up stones to stone him, but Jesus hid himself, slipping away from the temple grounds.
Reference to Old Testament - Exodus 3:14 God said to Moses, “I am who I am.[a] This is what you are to say to the Israelites: ‘I am has sent me to you.’”
The reaction of stoning Him shows that they realized the significance of what He was saying.
Jesus also refers to Himself as “the Alpha and the Omega, the First and the Last, the Beginning and the End.” a few times in Revelation (1:8, 21:6 and 22:13). God refers to Himself as the first and the last in Isaiah 44:6 and 48:12.
The Father, Son and Holy Spirit work together:
John 10:25 Jesus answered, “I did tell you, but you do not believe. The works I do in my Father’s name testify about me, 26 but you do not believe because you are not my sheep. 27 My sheep listen to my voice; I know them, and they follow me. 28 I give them eternal life, and they shall never perish; no one will snatch them out of my hand. 29 My Father, who has given them to me, is greater than all[c]; no one can snatch them out of my Father’s hand. 30 I and the Father are one.”
John 14:15 “If you love me, keep my commands. 16 And I will ask the Father, and he will give you another advocate to help you and be with you forever— 17 the Spirit of truth.
Hebrews 9:14 How much more, then, will the blood of Christ, who through the eternal Spirit offered himself unblemished to God, cleanse our consciences from acts that lead to death,[a] so that we may serve the living God!
I think the case is pretty clear. What is in the Doctrine of the Trinity that isn’t Scriptural? I don’t understand why this question of the Trinity keeps arising on these forums.
