No, it basically says Mary was a virgin. Nothing more.
I have my own opinion of her perpetual virginity but it doesn’t really make much difference in the grand scheme of things concerning her Son, so please ask yourself, what difference does it make to you? Are you asking to increase your knowledge? Or to further your own misguided idea of your authority over the authority Jesus established in His Church? If you read the discourse of the last supper, you should notice He tells His Church leaders that He will send the Holy Spirit to guide THEM, as His Church leaders, to all truth. He says nowhere He will do this for you or I. Yes, we interpret Scripture on our own, however if it is contrary to the interpretation of His Church, just whom did He guarantee would be led to all truth? His Church, not you, not I. I follow the teachings of the leaders of His Church, not because I feel they are smarter or better, or more holy, but because Jesus established it this way. Vanity is what keeps most people from following His Church, how can “they” tell me? They tell me because Jesus established it that way. I may not like the way He established His Church, but He is God, not me.
