Yeah, I reflected on that. This was a direct command from God on this one time event where He was going to interact with the people. Sort of like when Moses had to take his shoes off at the burning bush because the ground was holy (because of Gods presence). Do your priests wear shoes?
the priests try to leave the property that belongs to the Church to.
Right. That's when the Church was like our government. EVERYTHING should belong to them. So, if they're celibate they won't steal the silverware? Or hock the gold candlesticks at the local pawnshop type of thing? Sorry. I'm not buying it.
The shoe symbolism is an interesting parallel—in the culture, servants don’t wear shoes indoors—Moses, as a servant, approaching the Holy Place, should remove his shoes.
On the other hand, family does wear shoes in-doors—hence the prodigal son being shod. We are now sons—shoes are appropriate if one is to use shoes as symbolism.
In Exodus 19, the people are given a chance to be a Holy People, a Nation of Priests etc.—but they blow the optimal covenant opportunity of the time. They are given, IIRC, five conditions, and have clearly fulfilled three. The washing of the garments and the not touching women are the possible places that they have fallen down, and they are aware they have fallen down—they don’t go near the mountain.
God then says OK—not a nation of priests, I’ll set asside priests and give you something inferior, and then begins to speak to them directly until the people conclude this is going to be too hard and ask for something easier.
Abstaining from marital relations before partaking in sacrifice was standard under Judaism, and remained so when Christ completed Judaism. St. Pius X (1903-1914) was the one who abolished the three days of fasting from marital relations as a condition for receiving Holy Communion. If one has that in place and is to make the Bread available Daily, priests need to be celibate.
If they are celibate they won’t attempt to leave the cow and the chickens that belong to the parish for the sake of providing the priest with some of his food, and the land on which the animals depend, or the parish wood lot, to their children.
