The protestors would be well to pray on the fact that Jesus and nearly all of his earliest followers were Jews.
God has chosen to reveal Himself and His law or moral code to the Jews. Salvation is of the Jews (John 4:22) Jesus chose to live his earthly life as a Jew, and God has chosen to invite the nations of the world into a salvational covenant with Him by means of Jesus the Jew and by “grafting” the gentiles into the Jewish people (Romans 9-11 inclusive).
It is a mystery. The Church cannot fully explain it, neither can the Jews. And we are all still discussing and even debating the details of all this. But, this is how God has decided to deal with the world.
Inviting Jews and Protestant Christians into a cathedral or church to discuss matters of common concern does not mean the Church is abandoning its principles or teachings or faith. Indeed, would the protestors wish that no non-Catholics be invited to step foot into Catholic churches? Where would they find THAT kind of instruction or teaching in Scripture?
Do the protestors plan to continue to live on Rock Three, or do they wish to blast themselves off to some asteroid somewhere where they can live free of any contact or discourse or cooperation with people who happen to not be members of the RC Church and, perhaps, their unique little order?
uh, this wasn’t a “talk”; it was a ceremony.
Oh please oh please oh please Lord let that be so. ...the meek shall inherit the earth...
