it is complex situation and sadly some of the polemics from the SSPX are not helpful and can fuel a schismatic attitude, no doubt. But, I would say it is generally licit to attend (does not canon law allow us to go to Orthodox church?) unless the motivation is clearly schismatic.
I have a suspicion that if more orthodox Catholics would support the SSPX in some way at least and not support their heretical ordinary or priest, then that would help ease out many of the heretics and give Rome good reason to move these guys out quicker.
Incorrect. Catholics may attend Orthodox liturgies. Receiving communion is verboten, but attendance is not prohibited.
The Orthodox aren't excommunicated and haven't been since 1965.
I might have considered it at one time, but I've seen way too much selfish, childish, egotistical, pope-bashing trash-talking come from their leaders.
If they were hoping to attract the orthodox, they lost me early on.
PTP: Of course, if more orthodox Caholics found some way to adhere to SSPX, those Catholics would also cease to BE Catholic and would be volunteering for the schism itself.
