Why else do you think he gave them to us?
I don't think he gave you your brain to create your own Christian Church - along with dozens of others doing the same thing creating other churches.
Christ established His Church, the pillar and foundation of truth, with Him as the head, guided by the Holy Spirit, and the gates of hell will not prevail against it.
You don't have to create Christ's Church all over again, starting with one piece of the Church, the only piece which you use to derive meanings and beliefs far afield from His Church. and arriving at a theology contrary to those given to the Apostles by Christ and passed down through the Church by their successors.
This is rebelling against Christ.
To use your brain to attempt this is not using your brain well or wisely - as God intended.
