Eleven years after the third World Conference on Faith and Order at Lund, the fourth in the series (and, some have suggested, the last) was held in July 1963, at McGill University, Montreal, by invitation of the Canadian Council of Churches and with the active and welcoming participation of a Montreal Arrangements Committee. 498 persons attended the conference. 240 of these were delegates of the churches, 18 youth delegates, and 46 advisers invited by the W.C.C. There were 15 observers from non-member churches, including 5 from Roman Catholic Church, 3 from the Lutheran Church (Missouri Synod), and 1 from the Serbian Orthodox Church. There were 65 official guests, the great majority of whom had been invited through the good offices of the Canadian Council of Churches and the N.C.C.C.U.S.A. In all, 138 member and non-member churches of the W.C.C. were represented. Nor should we forget to mention in this list the 32 interpreters and translators who gave us their usual splendid service, and the 21 stewards who came at their own expense and who by their energetic work made the whole proceedings possible. It is well known that from the ranks of the youth delegates and stewards of one conference comes the chairman of the next conference but one, so that we should feel happy that the younger generation was so well represented at Montreal.
