Simply by eliminating communion in the hand, the attitude of the congregation improves immediately. And when it comes to attire, I often wonder how many of the people in shorts and flip-flops would attend a White House dinner in that attire. Whereas in Church, they meet the Lord of the Universe!
Like netmilsmom with her reverently worshiped NO liturgy, we have the same degree of reverence and respect in the Maronite Catholic Church. We have grown so accustomed to proper attire that when visitors show up wearing casual clothes, they become self conscious at how they stand out from the congregation.
Our parish allows communion in the hand (I don't think the pastor can forbid it, though we have no altar girls), but when I've been watching while waiting our pew's turn, I've noticed that the majority receive on the tongue. I'd estimate about two-thirds.
