That same blog has responses in the comments.

Where, for example, does it say Christians cannot drink in Holy places?

> Drink no wine or strong drink, you or your sons with you, when you go into the tent of meeting, lest you die.

-- Leviticus 10:9

Applies to Priests in the church/tabernacle, not other Christian participants of communion.

Also, the spicy tone of that blog isn't very charitable:

> 14. Drinking alcohol in holy places (bit of a problem for Catholics, this ‘un) (10:9) [“You will die.” May only apply to the priesthood.]

It almost certainly applies only to priesthood, given the audience of priests it was told to; and "lest you die" isn't the same as "you will die" which makes it seem like gods punishment for drinking.

The priesthood very much takes part in the Communion.

Hence "not other Christian participants of communion".

Some priest believe the wine is transformed into the literal blood of Christ, some don't.

For those that don't, I'm sure the "lest you die" is taken as meaning not to drink in excess.

The point is, the rule isn't "If you drink in a holy place, your punishment will be death".

> > Drinking alcohol in holy places

> That kind of goes against the holy communion

Not every church drinks wine for communion, many drink grape juice.

Yes I realize that and then they go against the New Testament teaching…
