The Council has also had an enormous impact on Anglicanism, especially on the Anglican understanding of the Church, its liturgy, ministry, mission, and approach to Christian unity. By opening Rome to ecumenical dialogue it made the work of the Anglican-Roman Catholic International Commission (ARCIC) possible. With a few bumps along the road, ARCIC has achieved significant convergence in several areas that previously separated our two traditions: eucharistic theology, ministry and ordination, justification, ecclesiology, and authority. In the spirit of ARCIC, Anglicans and Roman Catholics have come together locally in many practical ways, and their bishops have held conversations in various parts of the world under the aegis of a parallel but more recent body, the International Anglican-Roman Catholic Commission for Unity and Mission. A debate about the legacy and significance of Vatican II that may appear at first sight to be a purely internal issue for Roman Catholics is actually vitally important to Anglicans.
So what resources will enable us to understand what Vatican II had to say and what we can learn from it? The texts that the Council produced are available in English, Latin, and many other languages at is.gd/VaticanII. There are several English translations of the documents published in book form, including those by Walter Abbott, SJ (1966) and the generally superior edition by Austin Flannery, OP (1975, with subsequent revisions). The standard, authoritative translation is now that edited by Norman Tanner, SJ, Decrees of the Ecumenical Councils (Georgetown University Press, 1990), in two volumes with Latin and English facing each other on each page. But most of us are grateful for some guidance in choosing and understanding what to read. Tanner’s Vatican II: The Essential Texts has interesting introductory essays by Benedict XVI and James Carroll, as well as brief prefaces to each document. It is a handy size for carrying around and dipping into, but it contains only six of the sixteen documents produced by the Council.
Much more helpful to someone wanting to get to grips with the riches of Vatican II is the well-named Keys to the Council: Unlocking the Teaching of Vatican II by Richard R. Gaillardetz and Catherine E. Clifford.
