Me too but .. for so much study - you sure do not seem to know much about the Early Church. Your study has not been comprehensive . and is from a one sided perspective.
Even how the modern Trinity doctrine is stated in English is a rancid falsehood..
This is a standard statement of the Trinity "There are three persons within the Godhead; Father, Son and Holy Spirit. These three persons have equal status and are equally divine"
If you have studied the Trinity for 40 years .. tell me where the rancid falsehood is in the above statement ?
I will even give you a hint .. The Holy Spirit is not "A Person"
I know plenty about the early church and their heresies as well.

John 14-16 Holy Spirit distinct from the Father and Son and the PERSONAL PRONOUNS should give you a clue as to His PERSONHOOD.
John 14:16-17
16 "I will ask the Father, and He will give you
another Helper, that He may be with you forever;
17that is the Spirit of truth, whom the world cannot receive, because it does not see Him or know Him,
but you know Him because He abides with you and will be in you.
John 14:23
My Father will love him, and
We will come to him and make
Our abode with him.

the Helper, the Holy Spirit, whom
the Father will send in My name,
He will teach you all things, and bring to your remembrance all that
I said to you.

26 "When
the Helper comes,
whom I will send to you from
the Father,
that is the Spirit of truth who proceeds from the Father,
He will testify about Me,
27and you
will testify also, because you have been with Me from the beginning.
John 16:5-8
"But nowI am going to Him who sent Me; and none of you asks Me, Where are You going?'
6"But because I have said these things to you, sorrow has filled your heart.
7"But I tell you the truth, it is to your advantage that I go away; for if I do not go away,
the Helper will not come to you; but if I go,
I will send Him to you.
8"
And He, when
He comes, will
convict the world concerning
sin and
righteousness and
judgment;
John 16:13-15
13 "But when
He, the Spirit of truth, comes,
He will guide you into all the truth; for
He will not speak on His own initiative, but whatever
He hears
, He will speak; and
He will disclose to you what is to come.
14"
He will glorify Me, for
He will take of
Mine and will disclose
it to you.
15"All things that
the Father has are
Mine; therefore I said that
He takes of
Mine and will disclose
it to you.
Matt 28:19-20
Go therefore and make disciples of all the nations, baptizing them
in the name(singular not the plural names) of
the Father and
the Son and
the Holy Spirit
