I don’t know how that percolates down to the hypothetical scenario of a recalcitrant diocesan priest who attempts to play this trump card, and tell his bishop, “no, I’m not celebrating the OF, when I say Mass, it will always be the EF”. Just using my mother wit and sensus catholicus (such as it is), I would say that the obedience to his bishop, which he promised at the time of his ordination, would take priority — “yes, Father, that is true, you may always say the EF, but your ‘marching orders’ are, unless specified otherwise, where you have a congregation, to say the OF, because that’s what we do in this diocese, it’s part of your ‘job description’, so to speak”.
