*Excellent point. The Catholic Faith is all about deportment. If'n your in a schism make sure you follow the rubrics and all is jake.
"The Catholic Faith is all about deportment."
We are not talking deportment, we are talking sacriledge.
If you think the Mass is all about clowns and dancing girls,
you are part of the modernist establishment.
I choose to particpate in a valid, reverent Mass whenever I am able.
Taken from your own posting:
"The Masses they celebrate are also valid, but it is considered morally illicit for the faithful to participate in these Masses unless they are physically or morally impeded from participating in a Mass celebrated by a Catholic priest in good standing (cf. Code of Canon Law, canon 844.2 )"
It seems to me that sacriledge is a moral impediment to "participating in a Mass celebrated by a Catholic priest in good standing. "
Considering the state of the liturgy in many dioceses, thank God for the SSPX and the Eastern Orthodox.
