One of the most interesting words in the English language is hagiography. One of its definitions is the one I have in mind, an “idealizing or idolizing biography.” The idea is that once someone has died, we remember the individual as being better than he or she actually was. This adjusting of memory and idealization of those who lived before us is common throughout the human race.
But people “back then” were really not as wonderful as we think they were.
This is universally done with the folks who made up the very early church. Although the very early church had its strong points (the Apostles were around to teach and lead, God worked some unprecedented miracles like raising the dead, etc.), the people who made up the early church community were far from wonderful.
The case of Corinth
Consider the words of the New Testament itself about the believers who made up the family of faith. In Corinth, we notice a man sleeping with his stepmother (1 Cor. 5:1) while fellow Christians in the church accepted this brother as someone in good standing. The Corinthian church was divided into factions, each following the unique perspectives of a famous Christian leader (1 Cor. 3:4-5).
Things were so bad at Corinth that during their carry-in dinners members were consuming all the food before all arrived; some even became drunk while they waited (1 Cor. 11:21). The Corinthian Christians invented the “happy hour.” Read more about Were First Century Christians That Much Better?
