A Book of Collects in Two Parts was a collection of short prayers compiled by John Wallace Suter (Pater) and his son, John Wallace Suter, Jr. (Filius). Since the book was published in 1919, it is now in the public domain.
John Wallace Suter was a priest and liturgist in the American Episcopal Church, and was the custodian of the American Standard Book of Common Prayer. At his death in 1942, his son, John Wallace Suter, Jr. succeeded him as custodian of the Standard Book of Common Prayer.
