Jesus was perfect. Can you please show me one, just one, other man on this earth who is perfect in all things? If you can’t, then I think you will see the folly of your question.
“If not, then how can this church be true?”
That’s like saying, “Have you ever sinned? Yes? Then gee, I guess you’re not a Christian because Christ never sinned.” Does that make any sense? Nope. Neither does what you’re saying.
I guess you’ll leave your currect sect when the pastor makes a mistake or fails to go as far on a point as you would like, right?
If I learn that they ignored blatant evil for decade after decade, yes, I will leave. If I learn that they have deliberately and maliciously taught the worship of Marx instead of Christ to 2 or more generations of youth, yes, I will leave.
