How Often Should a Church Take the Lord’s Supper?

Jim Hamilton asks and answers the question above here. In the past I have basically agreed with the view expressed by Milliard Erickson that, "It should therefore be observed often enough to prevent long gaps between times of reflection on the truths it signifies, but not so frequently as to make it seem trivial or so commonplace that we go through the motions without really thinking about the meaning” (Christian Theology, rev. ed., p. 1134). But Jim makes a good point and I may have to rethink my position.
