That is fine - but what are they offering? Are they offering to change God's teachings to their liking or to have these people change to what God likes?
Just what was proven by the minister greeting them with a beer in his hand? Did it prove that God is a good ole drinker too? Did it say, "See, I believe and I can still hold a beer"?
I worry about the quick rush to change to make faith more "inviting" to those that don't bother to seek it in the first place. It starts a trend saying that we can't get them, so we must change to be what they will accept.
Where does that end?
If you see this as some kind of contradiction or hypocrisy on the minister's part, you obviously come from a strain of Christianity that regards consumption of alcohol as a sin.
As for making faith more "inviting," I see a vast difference between pandersing by changing the message and presenting the same message in venues that might draw more people in. The question is, how many 20-30 year old single people will show up at a theology lecture held in a church basement, versus how many will show up at the exact same lecture held in a popular bar?
Of course, if you belive that teetotaling is essential to being a Christian, then you'll see Theology on Tap or its protestant copycats as pandering to drinkers.
