I guess I put “any religion” because I don’t regard Biblical Christianity as “religion” but the truth! :-)
I’ve seen many, many comments in which people have denounced “religion,” claiming that “religion” is antithetical to faith in Jesus Christ.
Of course, Judaism was and is a religion. Jesus lived according to and in that religion.
By the “Christian Religion” or the “Catholic Religion” is meant merely that living in accordance with the truth about Jesus Christ and according to his teaching (which includes certain essentials of the Jewish religion) imposes certain obligations. The preaching of Jesus himself is chock full of calls to fulfill certain obligations. To love God. To love one’s neighbor, even one’s enemies. To pray in secret. To be chaste in thought, word, and deed. To take up one’s cross. Etc.
Consequently, I cannot buy the notion that believing in Jesus Christ means that one does not have or follow a “religion.”
