So, if our parish priest should demand something contrary to the demands of our diocesan bishop, we are not permitted to obey. Likewise, if our diocesan bishop demands something contrary to the demands of the Roman Pontiff, we are not permitted to obey.
Finally, with
special respect toward obedience to the chief pastor of the Church, the Roman Pontiff, the following saints and doctors have this to say:
St. Catherine of Sienna: “
Divine obedience never prevents us from obedience to the Holy Father: nay, the more perfect the one, the more perfect is the other.** And we ought always to be subject to his commands and obedient unto death. However indiscreet obedience to him might seem, and however it should deprive us of mental peace and consolation, we ought to obey; and I consider that to do the opposite is a great imperfection, and deceit of the devil.” (Letter to Brother Antonio of Nizza).
** St. Robert Bellarmine:** "…
the pontiff not only should not and
cannot preach heresy, but also should
always teach the truth, and
he will certainly do this since the Lord commanded him to confirm his brothers, and therefore he added: I have asked for you that your faith not fail, i.e. that the preaching of the true faith not fail in your see…Secondly it is proved from the result, for so far there has been no heretic, or certainly it cannot be proved of any that he was a heretic. Therefore it is a sign that
this cannot happen." De Romano Pontifice, Bk IV, Ch. 6]
** Ven. John Henry Cardinal Newman:** “*”**I say with Cardinal Bellarmine whether the Pope be infallible or not in any pronouncement, anyhow he is to be obeyed. No good can come from disobedience. ***
His facts and his warnings may be all wrong; his deliberations may have been biassed. He may have been misled. Imperiousness and craft, tyranny and cruelty, may be patent in the conduct of his advisers and instruments. But when he speaks formally and authoritatively he speaks as our Lord would have him speak, and all those imperfections and sins of individuals are overruled for that result which our Lord intends (just as the action of the wicked and of enemies to the Church are overruled) and therefore the Pope’s word stands, and a blessing goes with obedience to it, and no blessing with disobedience."[John Henry Newman “'The Oratory, Novr. 10, 1867”, The Genius of Newman (1914), by Wilfrid Ward, Vol II, Ch. 26]
St. Pius X: “And how should one love the Pope? Not merely by word nor tongue, but works and integrity. When one is loved, all of that person’s thoughts, wills, and desires are sought out for assent…
to demonstrate our love to the Pope it is necessary to obey him…when we love the Pope, …
we do not oppose to the Pope’s authority that of other persons – no matter how learned – who dissent from the Pope. For whatever may be their learning, they are not holy, for where there is holiness there cannot be dissent with the Pope.” [allocution of 18 November, 1912, AAS vol. 4 (1912), 693-695. Selection from p. 695]
If a person has multiple parishes near him, is it sinful for him to go to another church if his thinking/perspective matches up more with another area priest?
While I personally disagree with this kind of “parish shopping”, it may be permitted within current Church law, depending upon local diocesan norms. I personally believe the geographically closest parish is the family God intends for us to share in our worship, even if there are some “crazy uncles” in the parish clergy that one must suffer from time to time. If the preaching is contrary to doctrine, I figure I must be sent there by Divine providence to help teach him what
his pastor is teaching.

Nonetheless, one must weigh this against what may be the “greater evil” of harm done to one’s children being routinely exposed to heterodox or even heretical teachings.
Of course this gets somewhat back into the OP’ers question - how do you know you are legitimately dissenting/resisting rather than sinfully disobeying.
See my reference to St. Thomas Aquinas above.
I’m also wondering if the citations of canon law, DV, and LG do not beg the question as perhaps they are reformable in and of themselves.
Canon law and the constitutions they are based upon are not irreformable (excepting when they also touch upon dogma). However, until and unless revised by lawful authority, they are binding upon all Catholics.
Keep in mind to,
Lumen Gentium also gives the faithful this right and obligation:
By reason of the knowledge, competence, or pre-eminence which they have, the laity are empowered—indeed sometimes obliged—to manifest their opinion on those things which pertain to the good of the Church. If the occasion should arise, this should be done through the institutions established by the Church for that purpose, and always with truth, courage, and prudence, and with reverence and charity toward those who, by reason of their office, represent the person of Christ.*** The laity should, as all Christians, promptly accept in Christian obedience decisions of their spiritual shepherds***, since they are representatives of Christ as well as teachers and rulers in the Church.
[Vatican Council II, Dogmatic Constitution on the Church, Lumen Gentium, no. 37]
