The object of the homilies by St. John Chrystostom was to respond to an immediate need at the very time he was preaching, to dissuade Christian Judaizers from participating in Jewish ceremonies. For him this was an issue that was totally au courant, just as it was some 1,500 years later for Pope Benedict XIV, and just as it is for us, apparently, based on the reaction to Bishop Williamson's remarks.
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.
