Recently the online world has been filled with images of people in desperate conditions, images not from Pakistan or Syria but from the Greek islands closest to Turkey: Chios, Lesbos, Leros. One picture showed a migrant raft landing near sunbathing tourists on Kos, an island I once knew well. It was a way station on my yearly visits to the nearby island of Patmos, where St. John was once a refugee himself. I went there to visit another immigrant to Greece: a spiritual poet named Robert Lax, who was Thomas Merton’s best friend.
