Since the Church, according to the above quotation, clearly teaches that “it does not extend [the Eucharist] to those who on account of their tender age have not attained the use of reason,” why does it allow the Byzantine Rite churches to violate this rule?
There is no violation here of any rule that would apply to any of the Eastern Catholic Churches, Byzantine or otherwise. Let me clarify:
The Catholic Church, those faithful individuals who are in full communion with the See of Peter, is in fact a union of 23 separate Churches (the Latin Church, commonly referred to as the Roman Catholic Church - far and away the largest and best known of the Churches comprising the Catholic communion - and 22 separate Eastern Catholic Churches). Each of these 23 Churches enjoy the legal status known as “sui iuris” meaning “of their own law.” Each has as its head a single individual (in some cases a patriarch, in others a metropolitan archbishop; in the case of the Latin Church it’s the Pope himself).
In addition to being the leader of the Latin Church, the Pope, in his role as the successor of Peter,
also serves as the pastoral shepherd of ALL Catholics, Latin
and Eastern. This “dual role” that the Pope serves causes much confusion among the masses. It is commonly (and wrongly!) accepted that any “rule” enacted by the Latin Church (i.e. the Pope) must apply to all 23 Churches in the Catholic communion – this is grossly incorrect.
As I stated earlier, each of the 23 Churches that comprise Catholicism enjoys “sui iuris” status. Although each recognizes the Pope, *
in his role as pastoral shepherd of all Catholics, *as the earthly head of Catholicism, only the Latin Church is bound by those “rules” established by him
in his role as leader of the Latin Church. And, far and away, most of what he deals with on a day to day basis is specific to his sui iuris Church, the Latin Church.
Now, the “Church” that you refer to in the first sentence of your quote above is clearly the Latin Church,
not the entire communion of Catholic Churches. This (Latin) Church does not “allow” the Eastern Catholics, Byzantine or otherwise, to “violate this rule,” as you say, quite simply because her rules don’t apply to the Eastern Catholic Churches. She simply has no say in when the Eastern Catholic Churches may commune their young.
Despite its overwhelming majority within the communion of Catholic Churches (all 22 Eastern Catholic Churches
combined do not even come close to the size and magnitude of the Latin Church!), the Latin Church is
not the yardstick by which Catholicism is to be measured (despite what the media may have you believe).
Each of the 23 sui iuris Churches is
equal in honor to the other 22. And the rules established by each of the 23 sui iuris Churches are just as valid – just as
Catholic – as those of the others.
That’s what it means to be Catholic – unity, not uniformity!
