I'm not confused at all, but David Martin seems to be.
+Vigano is saying, "Don't leave the Church," meaning "Don't stop practicing [traditional] Catholicism just because others, including most priests, have hijacked the Faith." In which part that was quoted did Vigano say, "Do not leave your parish"?
A parish is a location. I wish people would stop being glued to specific locations. Be glued to the True Faith, the True Mass, and to those leaders who know the difference between the latter and New Church. If those happen to characterize your parish, then your parish is a safe place to stay as long as it continues not to waiver in those respects. Those locations could be an apostolate or an independent chapel. I didn't read that +Vigano said, "Do not go to an independent chapel." Did I read it too quickly?
