There are two main English editions of the Documents of Vatican II. The first—which I read as soon as it was published immediately following the Council in 1966—
was prepared under the general editorship of (pictured) Walter M. Abbott, S.J. It contains an extensive introductory note on the translation provided by the translation editor, Msgr. Joseph Gallagher.The introduction to the volume was written by Lawrence Cardinal Shehan, Archbishop of Baltimore, but it also includes a brief introductory essay by Bishop Reuben H. Mueller, President of the National Council of the Churches of Christ in the USA, entitled “An Adventure in Ecumenical Cooperation”.
Each document is prefaced and followed by comments from one scholar or another—priest or lay, Catholic or non-Catholic—except that the majority of the introductions are by Jesuits.The documents were presented in a kind of logical order, beginning with the Dogmatic Constitution on the Church, and ending with the Declaration on Religious Freedom. The edition was published by the Jesuit-run America Press.
