Justaservant,
I’ve written a few posts on this topic at
my blog.
Basically, there are two approaches to ecumenism:
- Religious liberalism
- Pre-eminence of Catholicism
Religious liberalism says that, more or less, all religions are equally good, and the difference is primarily in tradition, perspective, and ritual. This form of ecumenism has been repeatedly condemned by the Church.
The latter approach says that other religions have
some good and
some error. What is good and true we are to accept (eg: monotheism, opposition to abortion, etc.). What is evil and false we are to reject (eg: polytheism, human sacrifice). This has been the tradition of the Church from the patristic age onward. The early Church Fathers drew largely upon pagan writers such as Plato, Cicero, and Plotinus. They accepted what was compatible with divine revelation (eg. that God is beautiful), but they rejected what was not (eg. the pre-existence of souls).
That being said,
only the Catholic Church has the
fullness of truth, because Christ Himself, who can neither deceive nor be deceived, established the Church and revealed His truths to Her. The ultimate goal of ecumenism is to show others this fact. In other words, true ecumenism is evangelism.
Consider what St. Paul did in Athens: he praised the Greeks for worshiping the true, albeit “unknown” God, and then he explained to them who this God is: The God of Jacob, who became incarnate in the person of Jesus Christ!
What good ecumenists have done today is establish what we have in common and what we agree on, then dialogue from there. But it is important to remember that ecumenism is not merely “let’s all just get along” and “let’s all work together for social good.” It is good for us not to fight and for us to be able to work together for good, but we must not stop there! We must bring all people into the fullness of God’s truth found in the Catholic Church!
