Wannano:
My understanding is that the official Catholic position is that those not in communion with Rome are brothers and sisters in Christ.
Those not in ‘communion with Rome’ are our
separated brothers and sisters in Christ. By Baptism you are my brother in Christ, however, by not being in
full communion you are separated.
and that their churches/ecclesial communities are a means of providing salvation.
Providing sanctification, yes. Hearing truths in the written Word of God, yes. May non-Catholics be saved, absolutely. But, to say that non-Catholic Churches and ecclesial communities are a means of providing salvation undermines the ordinary and necessary means Christ established, through the licit Sacraments of the Catholic Church.
No longer is calling them “heretics” and all that accompanies that acceptable.
Context! I would never dare call anyone a heretic and/or schismatic for the sake of ecumenical charity. That does not mean that they don’t exist. Most heretics are
material heretics through no fault of their own and
may be saved. But, any grace that comes to them for possible salvation comes from the Catholic Church.
