The Church celebrates the memory of the martyrdom of these two
saints on the 5th of Abib, which is the 12th of July.This feast is called in
our Church by the name of "the feast of the apostles". Its date is
unchanged in every year.
The Church venerates these two apostles very profoundly; and
praises them and honors them exceedingly; especially in the prayer of "the partition" or "the division" which pertains to the fast of the apostles
and to the feast of the apostles, which we pray during the holy mass.
Although there are not many churches which are called by their two
names together, there is a church which is called by their two names in
the region of Amba Roueiss in Cairo, and another church which is called
by their two names in Los Angeles, California, USA.
