The Reformation Replaced the Monk with the Pastor's Family as the Christian Ideal

A key transformative act of the Reformation was Martin Luther's push for clergy to marry. This dethroned the celibate monk as the pinnacle of Christian devotion and elevated the married pastor and his family as the new, accessible model for all believers to emulate.

A Historian's Job is to Keep Society Sane by Unsettling Settled Facts

The Doctrine of Purgatory Was the Economic Engine for Building Medieval Cathedrals

The great cathedral-building boom was fueled by the theological innovation of Purgatory. This intermediate afterlife state, which could be shortened by prayers, created a massive market where nobles funded religious institutions in exchange for masses to save their souls, driving immense construction.

Christianity's Shift to Baptism Was a Radical Egalitarian Innovation

The adoption of baptism, a rite available to both men and women, over the male-only rite of circumcision from Judaism, represented a fundamental, built-in move toward gender equality at the very core of Christian initiation. This liturgical act affirmed equality from the beginning.

Christianity Adopted Monogamy from Greco-Roman Culture to Gain Influence

Contrary to popular belief, Christianity's monogamy isn't rooted in Judaism, which practiced polygyny. Instead, it was a strategic adoption of the prevailing Greco-Roman norm, a move crucial for the new religion to be taken seriously and spread within that society.

Clerical Celibacy Forced the Church to Redefine Lay Marriage Around Procreation

The 12th-Century Focus on the Eucharist Directly Caused Clerical Celibacy

Mandatory celibacy for Western clergy wasn't an early Christian rule. It arose in the 11th-12th centuries from a new theological emphasis on the Eucharist. The belief that priests physically handled Christ's body and blood created a powerful demand for their absolute sexual purity.

Pioneering Historians of Sexuality Like Foucault Were Warped by Their Catholic Views

Diarmaid MacCulloch argues that foundational historians of sexuality, including Michel Foucault, John Boswell, and Alan Bray, produced unreliable work.

St. Paul's View on Marital Equality Was Too Radical for Later Christianity

Paul's statement that a husband's body belongs to his wife, just as hers belongs to him, was an extraordinary assertion of physical equality in marriage for its time. Most subsequent Christian theology, particularly in the East, actively spiritualized or ignored this radical concept.

New Testament Gospels Downplay Jesus's Family to Justify Apostolic Succession

The Gospels' sometimes negative depiction of Jesus's family isn't incidental; it reflects a political victory by non-familial disciples (like Paul) over the dynastic faction led by Jesus's brother, James. The texts were written by the winners, who naturally minimized the authority of their rivals.
