Worshiping God can be accomplished without any affiliation to a religious organization, that's a common fact.
Being a member of a religious organization does not confer any special holy qualities. But in the area where we live (southeast U.S.), if someone becomes interested in associating with you, they want you to join their church. If you don't, they lose interest immediately. People around here will not be friends with you unless you are churchified. People in my age group, especially (60s).
Their apparent belief is that I just don't qualify as a good person if I don't strap on my pantyhose and show up at their church building at the prearranged time coordinates every week - and put money in their jar. They will be friends with me if I help them make the mortgage payments on their grandiose meeting facility.
That doesn't have anything to do with God. It's just a social club and it's too much trouble and those sermons make me sick because they are stuffed with hypocrisy and resounding with mind control. With friends like those, a person with any integrity would not sustain any spirituality - just nausea.
