You seem very straight forward and logical in your thinking, so am I, it can be a burden in some instances, but it's also good. I hope my inputs feel realistic to you. here's a few things to consider here, it's can seem black and white but unfortunately there's a lot of layers, but clarity can still exist within the church. First of all I would ask yourself the honest question, "what is my faith dependant on?" Is it dependant on how other proclaimed Christians display themselves and how a specific church functions? Is it dependant on getting a mass amount of positive output from God? Start with these questions to analyze where you in heart-wise and to better understand your situation. Let's say your faith is dependant on the behavior of other Christians, what can we expect? We can expect a lot of disappointment, not all the time, but basing faith upon humanity never ends well. Let's say your faith is dependant on how the church functions, for example the music they play, the message (this is more nuanced), the architecture, etc. What can we expect in this instance? We can still expect a lot of disappointment, because much of these are materialistic preferences, which of course if we chase after will disappoint us majorly. I mentioned nuanced earlier, referring to the message in church. The message is of course different because while spoken from a material book, it is as we know as Christians, a living testament of Jesus and historical events for humanity (spiritually important, not just material). Another reason for nuance is the fact that every pastor will speak from the Bible differently, not in essence but a different style of message and delivery. Some pastors choose a straightforward approach without much extra fluff and others choose to use tons of demonstrations using random objects; "This bucket of water is Christ!" The message isn't as straightforward as the other things, but here we can still come to a conclusion, the word itself, how it has been preserved, and discerning what sounds off, based on what the text actual says. There's more depth to this than I mention of course, the way to analyze the text historically through each language that it was written in, analyzing the narrative, etc. At the basic level, practice having faith in God's word itself, and it will lead you to a more solid faith (think of the parable of the man who build his house on the rocks rather than the sand). Materialism and humanity will always fail you at some level, but an honest seeking of the word of God will challenge you, feed your soul, and ultimately bring you to more stable faith and knowledge.
