In the Eastern churches it was
customary for some of them to preach in the presence of the bishop and
for the bishop to preach after them: and Valerius of Hippo was
consciously introducing an Eastern use into Africa—he was himself
a Greek, and therefore unable to speak fluently to his Latin flock—when
he commissioned his presbyter           “ against the custom of the
African churches” to expound the Gospel and preach frequently in his
presence.
