That what we know as the doctrine of the Trinity is the theological formulation of the teaching which began with the Apostles and continued into and through the early patristic period.
This is a very assumptive statement that you made and according to sources such as Encyclopedia Britanica, the Catechism of the Catholic Church, The New Catholic Encyclopedia, New Bible Dictionary 1982 and multiple other reputable sources, it is an incorrect one.
It is specifically stated that the Trinity was not a doctrine that was taught or implied by Jesus or his Apostles. Here is just one excerpt from multiple sources:
The New Encyclopedia Britannica – Micropedia – 15th Edition – Vol 11 – p. 928
“Neither the word Trinity, nor the explicit doctrine as such, appears in the New Testament, nor did Jesus and his followers intend to contradict the Shema in the Old Testament: ‘Hear, O Israel: The Lord our God is one Lord’ (Deut. 6:4). . . . The doctrine developed gradually over several centuries and through many controversies. . . . By the end of the 4th century . . . the doctrine of the Trinity took substantially the form it has maintained ever since.
This is just one of multiple reputable sources listed on my website.
The doctrine of the Trinity did not get its start from the Nicene or Athanasian Creeds; that's my point. It gets its start with the apostolic witness; that St. Paul never articulates what is finally formulated at Nicea, Constantinople, et al isn't the problem you think it is; because what is formulated at Nicea, Constantinople, et all is the result of what St. Paul did teach. It is St. Paul who says that in Christ is the fullness of Deity in bodily form, it is St. Paul (or at least someone speaking in his name) who declares Christ to be God (Titus 2:3), who says that Christ "though being in the form of God did not consider it robbery to be equal with God...". These Christological statements are present, and this same language is used as time continued, with St. Ignatius (for example) saying "Our God Jesus Christ" (Letter to the Ephesians, 18:2), "God Himself being manifested in human form for the renewal of eternal life" (ibid. 19:3); or St. Justin, "Christ being Lord, and God the Son of God" (Dialogue with Trypho, ch. 128). There is a continuum of faith and confession which is birthed in the experience of those who knew Christ, was preached by them, received by those to whom they preached, and who continued in their teaching--it is precisely this continuum and apostolic tradition that we see in the patristic writings and which, ultimately, is formulated in the Creeds and taught at length in the later fathers.
Contradictory to your statement, the Trinity did get its start from the Nicene and Athanasian Creeds according to reputable sources. I listed one source above, there are many more sources verifying this.
Here is another one:
New Bible Dictionary 1982
“The word Trinity is not found in the Bible…” “… it did not find a place formally in the theology of the church till the 4th century.” “… it is not a biblical doctrine in the sense that any formation of it can be found in the Bible…” “Scripture does not give us a formulated doctrine of the Trinity,…”
”
or
"
New Catholic Encyclopedia
“The word Trinity is not found in the Bible… It did not find a place formally in the theology of the church till the 4th century.” (The Illustrated Bible Dictionary) And a Catholic authority says that the Trinity “is not… directly and immediately [the] word of God."
Regarding the scriptures you brought out:
You listed Titus 2:3 but this scripture is talking about the conduct of older women. Perhaps you meant Philippians 2:6.
Philippians 2:6 is what is commonly called a "Trinity text". This scripture was talked about on my website. Upon reviewing the interlinear of this scripture and multiple translations one will see Trinity bias in translation in multiple mainstream translations of this scripture. This is one of the scriptures I pointed out under the section called "Trinity texts study".
There is not an Ephesians 18:2 or ibid 19:3 in the 66 books of the Christian Scriptures Bible
There is also no St Justin or dialog with the Trypho chapter 128
Perhaps you are talking about the "deuterocanonical/"apocryphal" books" of Catholicism or some other books. These apocryphal books are highly debatable whether they should be included with the current 66 books of the Bible or not. This is a highly debatable topic.
What is certain is right now, those things you quoted are not in the 66 books of the Christian Bible and their is a reason for this.
I must say, it seems strange that you came to a discussion forum not to discuss, but simply have people perform a spellcheck on your website.

Strange or not is debatable and relative. The truth is, getting assistance in getting my website proof read for errors and for ease of use is the exact thing I am searching for from multiple people. I wouldn't have asked for this if this wasn't the main point.
