A small fragment of faded papyrus contains a suggestion that Jesus may have been married.

The fragment, with just eight lines of text on the front and six lines on the back, is from a fourth-century dialogue, written in the Coptic language, between Jesus and his disciples. In it, Jesus speaks of “my wife,” according to Harvard professor Karen L. King, who discovered the fragment.

“The most exciting line in the whole fragment…is the sentence ‘Jesus said to them [his disciples], my wife…” King said in a video posted to Harvard’s YouTube channel. The next line of text reads, “She will be able to be my disciple.”

“This is the only extant ancient text which explicitly portrays Jesus as referring to a wife,” King wrote in her paper on the discovery.

The discovery, if it is validated, could have major implications for the Christian faith. The belief that Jesus was not married is one reason priests in the Catholic Church must remain celibate and are not allowed to marry. It could also have implications for women’s roles in the church, as it would mean Jesus had a female disciple.
