Father Daniel Savci, 55, was taken hostage by unidentified people at around 3 p.m.
They stopped his car as he was travelling to the Mor Yakup Monastery in a village near the town of Midyat.
The priest's kidnappers later telephoned a different church and demanded a ransom of 300,000 euros.
Turkish security forces had launched an operation to find the priest.
