This is fascinating:
Augustine died in 430. He was a theologian, philosopher, and the bishop of Hippo Regius in Numidia, Roman North Africa. His writings influenced the development of Western philosophy and Western Christianity, and he is viewed as one of the most important Church Fathers of the Latin Church in the Patristic Period. His many important works include The City of God, On Christian Doctrine, and Confessions.
The marriage between Muhammad and A’isha should be considered on the same grounds. To judge an incident nearly 1400 years old by today’s standard (!) of sexuality, without considering geographical and cultural issues of that time, is anachronism and ignorance at best.
