Jesus teaches us what is right and what is wrong and gives us the power to do the right and reject the wrong. Jesus is the one who gathers us into a community of faith, which learns together, prays together, obeys together, and suffers together. Jesus himself is the builder of this new community, this ecclesia. For God’s gathered community the central question is, “Are we living in the life and power in which the apostles lived?” 

If we have this, nothing else is needed.
