Well personally -
I have issues with most so called “churches”. They almost always end up focusing on the internal politics or some level of minutiae rather than the Gospel. So I’m a Bible reader (listener on my 1hr daily transit) and not a church goer.
The Trinity has always confused me since I was a Kid. I understand the idea and theory, but I struggle with the whole 3 separate = 1 idea. Especially when some verses seem to indicate strongly that the Son is subservient to the Father. I accept it on faith and faith alone - because otherwise it makes my head hurt.
If you haven't already encountered this, recognize that when The Son came to earth He set aside His co-equal status and placed himself in the position of being subservient to The Father, as a Son should be. But when He finished His earthly tasks as a servant of the Father and returned to Heaven, He resumed His former prerogatives as co-equal status. The Three are always in agreement, but some of their distinguishing functions and manifestations are different, indicating their Personality.
The scriptures recording His earthly ministry of fulfilling the Law Covenant refer to this period in which His subservience was a necessary feature. Don't confuse them with other passages in which He is not subservient, but rather co-equal with separate functional aspects.
I hope this viewpoint helps smooth out your perplexity.
As far as the Trinity confusing you, you are not alone. It is impossible to understand it. We can only accept it. That is what makes it so true, because if someone was trying to create a god, they certainly wouldn't have created a being that is next to impossible to understand.
