To question or disregard JPII's teaching on this issue (and others like it) is not to become schismatic, or heretical, or any of the other names you toss out for anyone who doesn't agree with his every word and act.

When the grounds are clear and cogent, when they are shared by a number of serious and loyal theologians, then it is permitted to differ from the decree or at least to withdraw one's agreement for the present time. But it is not permissible, out of respect for the holy power of the Apostolic See, to take a public position against it; rather, one should undertake a respectful silence, or the difficulty may be presented to the Apostolic See. (F. Gallati, "Wenn die Papste Sprechen", Vienna: 1960, p. 175)

Here's His Holiness Pope Leo XIII's statement on this subject:

"The woman, because she is flesh of his flesh, and bone of his bone, must be subject to her husband and obey him; not, indeed, as a servant, but as a companion, so that her obedience shall be wanting in neither honor nor dignity."
