No More Learning

The canons of Sardica, probably because of the
occurrence in them of the name of Hosius of Cordova, are in most of
the oldest collections joined without break to the canons of Nicaea :
and a rather acrimonious controversy was carried on between Rome and
Carthage in the years 418 and 419, because Pope Zosimus cited the
Sardican canons as Nicene, and the Africans neither found these canons
in their own copies nor could learn           about them in the East.
