This up-to-date treatment of the sacraments is written by a modern master of theology. Fully ecumenical in spirit, the book gives a contemporary understanding of the sacraments, including the origin and history of each.
John Macquarrie FBA TD was a Scottish-born theologian and philosopher. Timothy Bradshaw has described Macquarrie as "unquestionably Anglicanism's most distinguished systematic theologian in the second half of the twentieth century."
Very informative book on the Anglican Sacraments. The chapter on Marriage is quite outdated though but a lot has changed in that regard since the 90s when it was published. Overall though a very very good read.
