If LG 16 refers to a hypothetical case it is not a rupture with EENS and so supports the old ecclesiology of the Church
Are you joking? Lets assume LG 16 is not heretical against EENS. Then it is still a rupture of the Dogma of the Incarnation and the Dogma of the Holy Trinity. Do you understand?
If LG 16 is not a rupture with EENS , if it refers to a hypothetical case, then it supports the old ecclesiology. If it is not a rupture with the old ecclesiology then how can it be a rupture with the dogma of the Incarnation and the Holy Trinity ?
