I am sure they would not admit you to their fellowship!
"Let us consider how we may spur one another on toward love and good deeds. Let us not give up meeting together, as some are in the habit of doing, but let us encourage one another — and all the more as you see the Day approaching." Hebrews 10:24-25
If you wait until you find a perfect church — then you must wait until you get to Heaven.
Even if you could find a perfect assembly on earth, I am sure they would not admit you to their fellowship, for you are not perfect yourself.
Find out those people who are nearest to the Scriptures, who hold the truth in doctrine and in practice, and are most like the New Testament church — and then cast in your lot with them, and you will be blessed in the deed.
