HWA taught that God is a family presently composed of the Father and the Son. He also asserted that this was the teaching of the original apostolic church.
If this is true then why does the Didache, in Chapter 7, echoes Matthew by saying new Christians are to be baptized "into the name of the Father, and of the Son, and of the Holy Spirit" as may be seen here.
And concerning baptism, baptize this way: Having first said all these things, baptize into the name of the Father, and of the Son, and of the Holy Spirit,Can HWA really be so sure that the apostolic church taught the God Family doctrine?
It also needs to be said here that there was no dark century as HWA taught. I strongly encourage you to read the previous link if you think there was such a dark age.
