Fr G is not a red lighter. He told the Langley faithful that it is ok for now to attend the local SSPX Chapel.
How he is going to manage people who ask him if they should still attend SSPX Chapels is a different story that does change the fact he himself is a red lighter.
But I'm afraid the best form of teaching is by example.
Yes, I think there is a difference between what he does as a priest and where laypersons stand with regards to reception of the sacraments.
It is the responsibility of the priests to stand up strongly against the new orientation but at the same time laypersons can't be going nilly-willy without the sacraments. If they have a resistance chapel nearby, then by all means attend. If they do not, then it gets a bit more complicated.
