OK, you have a point with both your recent posts.
There is a necessary tension between the two faiths. Depending on the historical moment, it can heighten or lessen. Obviously, the homilies of St. Peter are not going away, and they are very condemning.
Now, are the remarks of bp. Williamson and the priests at the head of the thread today, and in SJackson's link reflective of such moment of greater tension?
I think, the real tension today is with the democratic social system that tends to neo-paganism. When these SSPX people insert an ethnic element, that is a false note. The exponents of carnality today are hardly the religious Jews of the same tradition that condemned Jesus. Sure there may be Jews among the "carnal" people, but also they may be cultural/ethnic Catholics. In the culture wars we have an ally in conservative religious Jews.
I would add that there are apostolic constitutions forbidding priests to pray in non-Christian houses of worship, and other similar measures aimed at liturgical separation, and generally syncretism is a heresy.
The recent popes were criticized by traditionalists for appearing at synagogues and mosque(s), although it is doubtful that canon laws were broken, as there was no prayers in common.
That, of course, is internal church matter and not a matter of social teaching.
Agreed.
