Beck 1950: 132, n. 23 suggested that in order for the second part of this canon to be reasonable, it must be assumed that there can be several masses celebrated daily at the same altar, and that one presbyter can offer sacrifice at two altars on the same day. The prohibition applies only to saying two masses at one altar in quick succession.
This canon testifies to the intensification of Eucharist celebration in the second half of the sixth century. It seems that some priests celebrated numerous masses daily. The introduction of such precepts coincides with the first evidence on multiple altars in one church, see [2313].
