Then you need to do your research.
Based on the speculative nature of all of the responses given here, that is precisely what it is based on.
The responses here have been in reply to the tenor and direction of your questions. That’s why they haven’t addressed the Church’s reasoning. But, if you tool around the site, I’m sure you’ll find an explanation of the term ‘
brethren of the Lord’.
Again, the reading away from the natural reading provided by Matthew is pure speculation.
That depends on whether one agrees that the
strict ‘uterine’ reading is the “natural reading.” The Scriptural references that show other readings diminish your claim that it is.
The only arguments put forward in defense of this thus far offer no positive confirmation of the perpetual virginity, they only try to change the clear meaning of the text to say its possible.
You’re misreading the arguments, then. You’ve asserted that we
must read it in the way that you read it. The arguments against your claim demonstrate that this is not true – it
is possible to read it other ways.
What they’re doing is dismantling your argument, not proving theirs. And, with your argument destroyed… well, you have no grounds to stand on to dismiss the Catholic argument, now do you?
And again, with regard to the claim that this was the universal teaching of the Church, no it wasn’t.
It was. Let’s look at your ‘facts’:
I submit the fact that Jerome had to debate it with Helvitius in the 4th-5th Century
Helvidius’ problem was with the ascetical movement in the 4th century Church, which asserted that virginity was superior to marriage (and thus, argued that Christians should adopt virginity, or at least, admit that virginity trumped marriage). His work (which is not extant) is quoted by Jerome. He was responding to an essay that asserted that virginity was superior to marriage, and that Mary’s perpetual virginity proved that point. He argued against that point, and in doing so, also argued against Mary’s perpetual virginity. See Hunter’s essay
Helvidius, Jovinian, and the Virginity of Mary in Late Fourth-Century Rome for more details.
In any case, one dissenter does not prove that there was not a doctrine. Here’s your counter-example: anecdotally, it’s claimed that half the Catholics in the U.S. do not follow the Church’s teaching against birth control. Would you use that factoid to demonstrate that the Church
doesn’t teach against birth control? Of course not! Similarly here – you can’t use the witness of one, or ten, or one hundred dissenters to prove that a Church teaching doesn’t exist. That kind of anecdotal evidence doesn’t prove anything.
