A title of address meaning 'master' or 'overseer,' used exclusively in Luke's Gospel as a way disciples speak to Jesus. While Matthew and Mark use 'Rabbi' or 'Teacher' in parallel passages, Luke consistently chooses epistates, a term drawn from Greek civic life where it denoted an overseer, superintendent, or commander. Peter addresses Jesus this way when called to let down his nets (Luke 5:5), the disciples cry out to him during the storm (Luke 8:24), and Peter uses it at the Transfiguration (Luke 9:33). The multilingual glosses — Spanish 'Maestro,' French 'maitre,' German 'Meister' — all gravitate toward 'master' rather than 'teacher,' reflecting the word's emphasis on authority and oversight rather than instruction alone.
