That was an extended version of ''believe what you want and ignore the rest.''You are conflating to different terms and ideas.
To be "Christian" means to be Christ-like in action and deeds. That can be done by any sect of Christianity if they so choose to. Some don't. That's about "the right kind" of Christians. Then, there is the Christian Church that has the "true Gospel" meaning has all the power and authority of Jesus Christ with all the correct ordinances for salvation and exaltation. All churches have a few or some of the knowledge, but lack the authority to perform the ordinances like baptism and the binding power of Elijah of husbands and wives and families for exaltation. How many churches claim that Elijah has already returned with the power to bind our ancestors with us and have the authority to do so? Only one. Same one that baptizes for the dead as well.
