The History of Sex: Geneva -- Marriage: The Healthy Alternative? -- (Chap. V, Pt. 2)

Luther and his fellow Reformers railed against Rome's corruption and preached marriage as a healthy alternative to celibacy.

Within five years, Luther's Swiss counterpart, Zwingli, openly committed heresy by marrying, breaking five centuries of tradition within the Catholic Church.

And in 1525, Luther himself went one better by tying the knot with a former nun he'd helped smuggle out of a convent.

The excommunicated Augustinian broke with the teachings of St. Augustine when it came to marrying his twenty-six-year-old bride.

By all accounts, Luther was still a virgin at the age of forty-two and, rather than 'descending with a certain sadness' into their matrimonial bed, he and Katharina seem to have gladly hopped to it.

They had six children, raised four orphans and had a very happy marriage—even though Luther could be a bit of a boor.

(Martin liked to call her 'My lord, Katie')

A student recalled him teasing 'Katie' at the table, announcing: 'The time will come when a man will take more than one wife. A woman can bear a child only once a year while a husband can beget many.'

'Let the devil believe that!' she replied, quoting the Bible to him: 'Paul said that each man should have his own wife.' 

But the theologian kept on kidding her, noting that Paul had written 'his own wife;' not his 'only wife.'

'Before I put up with that,' Katie shot back, 'I'd rather go back to the convent.'
