The chief aim of this primer is to give the student, within one year of study, the ability to read ecclesiastical Latin. Collins includes the Latin of Jerome's Bible, of canon law, of the liturgy and papal bulls, of scholastic philosophers, and of the Ambrosian hymns, providing a survey of texts from the fourth century through the Middle Ages. An ""Answer Key"" to this edition is now available. Please see An Answer Key to A Primer of Ecclesiastical Latin, prepared by John Dunlap.
