Jesus is our only Teacher, Yahweh is our only Father. To get absolute truth we rely on quoting the scriptures verbatim.
However, there are:
1. Topics God and Jesus did not cover
2. Various understandings of the same passage
3. Question on how to apply True Scripture to life in the 21st Century
For these categories Disciples are free to discuss openly as long as they make it clear that what they are saying is their opinion.
Truth: “Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit” – Matthew 28:19
Opinion: “Because it say father ,son, and the Holy Spirit, this means God is a trinity”. because this sentence is spoken as a Truth by so many Christians (who learned it from someone else), we are actually sinning against God and men. We are writing scripture and making ourselves into a god. How dare we add to Yahweh’s words, or the words of the Messiah Jesus.
