I don't see why it would take 11 years or more to figure out if one was attending a good church. It should take no more than a couple of months.
Jesus most certainly had rules, as did the Apostles (all ESV):
Matt. 16:24 Then Jesus told his disciples, "If anyone would come after me, let him deny himself and take up his cross and follow me."
Matt. 18:1 At that time the disciples came to Jesus, saying, "Who is the greatest in the kingdom of heaven?"
2 And calling to him a child, he put him in the midst of them
3 and said, "Truly, I say to you, unless you turn and become like children, you will never enter the kingdom of heaven.
4 Whoever humbles himself like this child is the greatest in the kingdom of heaven.
5 "Whoever receives one such child in my name receives me,
6 but whoever causes one of these little ones who believe in me to sin, it would be better for him to have a great millstone fastened around his neck and to be drowned in the depth of the sea.
...
8 And if your hand or your foot causes you to sin, cut it off and throw it away. It is better for you to enter life crippled or lame than with two hands or two feet to be thrown into the eternal fire.
9 And if your eye causes you to sin, tear it out and throw it away. It is better for you to enter life with one eye than with two eyes to be thrown into the hell of fire.
...
15 "If your brother sins against you, go and tell him his fault, between you and him alone. If he listens to you, you have gained your brother.
16 But if he does not listen, take one or two others along with you, that every charge may be established by the evidence of two or three witnesses.
17 If he refuses to listen to them, tell it to the church. And if he refuses to listen even to the church, let him be to you as a Gentile and a tax collector.
...
21 Then Peter came up and said to him, "Lord, how often will my brother sin against me, and I forgive him? As many as seven times?"
22 Jesus said to him, "I do not say to you seven times, but seventy times seven.
Matt. 19:13 Then children were brought to him that he might lay his hands on them and pray. The disciples rebuked the people,
14 but Jesus said, "Let the little children come to me and do not hinder them, for to such belongs the kingdom of heaven."
Matt. 28:18 And Jesus came and said to them, "All authority in heaven and on earth has been given to me.
19 Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit,
20 teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age."
