It's not like the various Christian churches invented those frameworks from scratch either. They are assimilated and developed from existing practices. The church has no monopoly over these practices. The secular community can take -- and has taken -- these practices and develop them into a secular framework. For example, my wedding, and those of most of my friends, were secular. They were very much similar to the religious weddings in my culture, but the official part was done in front of a judge instead of a priest.
