Sorry, everything in the Bible that is written about Mary and Joseph points to the fact that they were a married couple in every sense of the word.
:-)
As unScriptural as Mary's perpetual virginity is, the RC contention that she lacked Original Sin and rose bodily into heaven are truly mystifying and border on blasphemy, IMO.
From Wikipedia...
"According to Roman Catholic doctrine and the traditions of the Roman Catholic Church, the Blessed Virgin Mary (Mary, the mother of Jesus) "having completed the course of her earthly life, was assumed body and soul into heavenly glory." (Pope Pius XII, Munificentissimus Deus, November 1, 1950). This means that both Mary's soul and her physical body were transported into heaven. Mary's passage into heaven is called Assumptio Beatæ Mariæ Virginis (Assumption of the Blessed Virgin Mary) by Roman Catholics. This doctrine was dogmatically defined by Pope Pius XII on the 1st of November 1950."
