No less than the NIGTC says of this:

That said, there are varying interpretations and contra-indications to such a plain instruction. (2 John being addressed to "the elect lady and her church" comes to mind.) But, if the standard interpretation is the sensus plenior here, then the Bishop of Rome would simply being saying that the church has no authority to create a new teaching out of a very old Scripture.

This was precisely the view of John Chrysostom (the Golden Mouth), who in full 4th century fair writes:

“But I suffer not a woman to teach.” “I do not suffer,” he says. What place has this command here? The fittest. He was speaking of quietness, of propriety, of modesty, so having said that he wished them not to speak in the church, to cut off all occasion of conversation, he says, let them not teach, but occupy the station of learners. For thus they will show submission by their silence. For the sex is naturally somewhat talkative: and for this reason he restrains them on all sides. “For Adam,” says he, “was first formed, then Eve. And Adam was not deceived, but the woman being deceived was in the transgression.” If it be asked, what has this to do with women of the present day? it shows that the male sex enjoyed the higher honor. Man was first formed; and elsewhere he shows their superiority. “Neither was the man created for the woman, but the woman for the man.” (1 Cor. 11:9.) Why then does he say this? He wishes the man to have the preëminence in every way; both for the reason given above, he means, let him have precedence, and on account of what occurred afterwards. For the woman taught the man once, and made him guilty of disobedience, and wrought our ruin. Therefore because she made a bad use of her power over the man, or rather her equality with him, God made her subject to her husband. “Thy desire shall be to thy husband.” (Gen. 3:16.) This had not been said to her before.

And, this is not just 4th Century prejudice. No less than the NIGTC (The New International Greek Testament Commentary) says of this:

That said, there are varying interpretations and contra-indications to such a plain instruction. (2 John being addressed to "the elect lady and her church" comes to mind.) But, if the standard interpretation is the sensus plenior here, then the Bishop of Rome would simply being saying that the church has no authority to create a new teaching out of a very old Scripture. After all, the order of things was established far before him, and woe betide the one who tries to change it.

Whether or not one agrees with the interpretation, there is a reasonable biblical case to be made that a woman should not preach or teach in the church. Paul writes in 1 Tim 2:

8 I desire then that in every place the men should pray, lifting holy hands without anger or quarreling; 9 likewise also that women should adorn themselves in respectable apparel, with modesty and self-control, not with braided hair and gold or pearls or costly attire, 10 but with what is proper for women who profess godliness—with good works. 11 Let a woman learn quietly with all submissiveness. 12 I do not permit a woman to teach or to exercise authority over a man; rather, she is to remain quiet. 13 For Adam was formed first, then Eve; 14 and Adam was not deceived, but the woman was deceived and became a transgressor. 15 Yet she will be saved through childbearing—if they continue in faith and love and holiness, with self-control.

A theological justification for the point then is this - Eve was deceived, and therefore all women can no longer be trusted. It is, in fact, Scriptural, using a very plain sense reading of the text.

No less than the NIGTC says of this:

Some have suggested that Paul conveys here only a note of personal disinclination (cf. Phillips’s translation: “Personally, I don’t allow”). But such a suggestion misunderstands the authoritativeness of ἐπιτρέπω when used by Paul (cf. Robertson: “Paul speaks authoritatively”), which is demonstrated by a close analysis of the three occurrences in Paul (1 Cor. 14:34, a parallel; 16:7, an action of the Lord; here). The strength of the prohibition here is underlined by Paul’s appeal to the creation order (v. 13, γάρ); in 1 Cor. 14:34 the prohibition is correlated to “the law” (undoubtedly the same OT teaching as here in v. 13) and is further delineated by his covering statement in v. 37, “the things that I write to you are the Lord’s commandment.”
