Early Latin Theology presents seven of Bernard Lonergan's most important early theological works in English translation and the original Latin on facing pages under one cover for the first time. First composed as supplements to the texts he used in his courses, these writings are considered to be Lonergan's initial efforts in the functional specialty he would come to call 'systematics.' They also represent ideas that would remain constant throughout his career.

Among the significant works included is 'Supplementary Notes on Sanctifying Grace.' This seminal essay contains what is likely Lonergan's most complete systematic treatment of the topic, and a much more extensive presentation of Lonergan's four-point hypothesis regarding the divine relations and created grace than many have previously read.
