The Last Gnostics Still Baptize Every Sunday

Mandaeans call any river fit for baptism a Yardena, after the Jordan. The water has to be flowing, never still, because for them it carries the living world from the realm of light into a fallen one. Every Sunday, white-robed believers wade in, the priest dips them three times, traces the forehead three times with water, and hands them three drinks. Then a piece of bread, a sip of water, and they are clean again until next week.

They trace this rite to John the Baptist, whom they call their final and greatest prophet. Jesus, in their telling, was a Mandaean priest who learned the practice from John, then broke away, took it to outsiders, and corrupted it. Adam, Seth, Noah, and Shem are prophets too. Muhammad is not. Their scripture, the Ginza Rabba, is written in a script and dialect of Aramaic that has no other readers in the world.

For most of two millennia they survived in the marshes of southern Iraq and Khuzestan in Iran, tolerated under the protection of the Quranic category 'Sabian'. The 2003 Iraq War tore that apart. By 2007 the Iraqi community had collapsed from an estimated 60,000-plus to around 5,000, with the rest scattering to Jordan, Syria, Sweden, and Australia. Priests have to be born into priestly lineages, and they need rivers, so the diaspora keeps improvising in pools and the occasional artificial trough.

The Yardena keeps moving. The community trying to stand in it gets smaller every year.
