[Maximilian]

True ecumenism is not religious syncretism or relativsm

If it walks like a duck, and quacks like a duck, and defecates like a duck, then I say that it is a duck.

does not compromise the teachings of the deposit of faith

True or false -- Jews do not need to convert to the Catholic faith because their own covenant is salvific for them? This is what is being taught today. I say that it DOES compromise the teachings of the deposit of faith.

[Unam Sanctam]

If it is salvific, it is salvific through Christ, but I don't think the matter is settled yet, and I am no expert on the matter. There was uncertainty about the immaculate conception for many centuries, remember.
