Here is a post from American Papist on Bishop Wuerl's appointment to Washington.
When I was first teaching the permanent Deacons in the South of England, I used to recomment Wuerl's The Teaching of Christ. This was only superseded by the publication of the Catechism of the Catholic Church. I remember that it came out in French long before the English version. I used to translate sections for the students.
Bishop (soon to be Archbishop, and, please God, Cardinal) Wuerl was secretary to the great Cardinal Wright who did so much to support sound catechesis in the 1970s.
