The Marian Dogma of the perpetual virginity of Mary is not something well-accepted or understood today.
The grace of God in Mary’s life has to be something of acceptance and not of understanding maybe. The majority of people only embrace a life devoid of sexuality very late in life.
For those close to God, as Mary was close to God, it is revealed that spiritual union far surpasses physical union. While marriage is right for most people, it is not the only way to happiness and a fulfilled life.
