I want to know the answer to the following question:
For what purpose did detractors use the idea of Mary's virginity and the virgin conception of Jesus?
All the background I'm provided with is that "From the early stages of Christianity, belief in the virginity of Mary and the virgin conception of Jesus, as stated in the gospels, holy and supernatural, was used by detractors, both political and religious, as a topic for discussions, debates and writings, specifically aimed to challenge the divinity of Jesus and thus Christians and Christianity alike.". Is that enough to answer the question?
