I don’t think this “discovery” was made in order to make up a more suitable Jesus, but rather to obfuscate the knowledge of the real One.
Actually, they are attempting to do both. They need a homosexual Jesus, a whore-mongering Jesus. They need him to be a married liar. They need a Jesus who says one thing and does another. All to justify their own sins. In the process of creating their own personal Jesus they work to make the Real One look like a chump. It's a two-fer.
