A bit of reminiscing seems appropriate on this anniversary occasion.2 The Institute of Liturgical Studies was founded by true pioneers in the liturgical movement. The blessings granted to that movement in terms of its achievements are awesome. I don't know if anyone counted such things in the 1940s, but in the decade in which the Institute of Liturgical Studies was founded there were not a hundred congregations in all of North American Lutheranism where there was a weekly Eucharist.
