I want to know the answer to the following question:
Which doctrine describes the belief that Mary remained a virgin, even though she gave birth to Jesus?
All the background I'm provided with is that "The term Ever-Virgin (Greek ἀειπάρθενος) is applied in this case, stating that Mary remained a virgin for the remainder of her life, making Jesus her biological and only son, whose conception and birth are held to be miraculous.". Is that enough to answer the question?
