From a reader:
When [receiving Holy Communion] in the Extraordinary Form Mass is one required to observe the older fast (as opposed to the 1 hour fast required for the OF)?
If so, how many hours of fasting is required?
No. You are not required to keep a Communion fast according to the old laws. You are required to observe it according to the law presently in force.
The law at present, for Latins at least, says one hour before the reception of Communion. That is, not before the beginning of Mass, but before Communion.
Of course you are free to do more than that. In the old days, three hours became the length of time for the Eucharistic fast. Before that, it was from midnight. All this was changed. The 1983 Code is in force now.
We must be properly disposed to receive.
We are creatures of both soul and body. Both need their disposition.
The spiritual disposition is being in the state of grace.
The physical disposition is fasting beforehand for the length of time determined necessary by the Church.
Holy Church would do well to return us to a three hour fast.
Making it just a little harder might help people understand that what they are doing is important, and it has consequences.
A longer fast (i.e., making things just a little harder) would help to increase both our sense of the importance of the Eucharist and also our own need to be properly disposed, spiritually and physically, to receive.
But no one has asked my input about that.
