Are you talking about a denomination or belief system?
Our 'instruction' needs to be in God's Word. The first time I actually read straight through my Bible , I could easily see where various groups got their basis 'from'. It was landing in various Scriptures and staying 'there' and not taking other passages into consideration.
And a person can see all kinds of churches in most every community.
So -- where is a person feeling led to go To church. Well -- does the pastor teach straight Bible / salvation - shed blood of Christ plus nothing on our part -- missions outreach into community -- baptism by immersions. The age factor of your family. Kids need other kids to associate with -- teens need teen-agers. Young married's need other young married couples.
There had been a young couple who met through a particular church -- they stayed there for a long time -- then they got pregnant -- no other young expectant couples around. The husband's brother and family went to another church across town. Lots of young couples with young families. So -- talked with pastor and said he felt they Now needed to be with other young families. So -- they left and went to the other church. That was a good move on their part.
Another family with four daughters -- a very small church but with good teaching. They stayed put and the pastor made sure that he was never alone with any of the daughters even though he did teach that 'age group'. They had moved from another larger area and their family had grown over the years. But there were no other churches in the area that were teaching Bible. Personally, I would have moved to another area With more young people.
I suspect you're talking about Methodist, Lutheran , Presbyterian, Baptist groups. My oldest granddaughter went from sort of a non-denominational group to a large Presbyterian church where her to-be husband went. A good , sound church. My grandparents were Presbyterians -- My folks changed to Baptist. Baptism by immersion. They were all believers.
