Book excerpt: In his translation entitled "The Catechetical Instructions of St. Thomas Aquinas," the Rev. Joseph B. Collins, S.S., S.T.D., Professor of Theology and Catechetics at the Catholic University of America, has made available to teachers of religion a theologically accurate explanation of the Catechism. It is Dr. Collins' latest contribution to the catechetical movement in America. The appearance of this translation of St. Thomas' catechetical works will be greeted with genuine satisfaction by all. In these days of renewed interest in Thomism, especially on the part of laymen, it will be comforting to know that the vast knowledge of the Church's greatest theologian is now made accessible--in a condensed and simple form--not only to teachers of religion but to the laity at large.
