ONE body
ONE hope (which is both heaven AND earth, since we will be LIKE Jesus having access also to higher dimensions)
ONE faith
ONE flock
ONE baptism (including being baptised by Holy Spirit)
Priesthood and sainthood of ALL believers. A right (righteous) and clean (holy) standing is IMPUTED as a free gift by grace and faith (in Christ) and not by any merit or membership (of a particular sectarian or denominational group or organisation).
Every member organically (naturally) and authentically functioning BODY. No clergy (FDS/GB/hierarchy) versus laity (other sheep, great crowd). "Unity in Christ" instead of contrived "unity in doctrine". No pretentious and supremacist legalism, moralism and so on.
Eph 2:6; 4:4,5; John 10:16.
