16 The study of sacred liturgy is to be ranked among the compulsory and major courses in seminaries and religious houses of studies; in theological faculties it is to rank among the principal courses. It is to be taught under its theological, historical, spiritual, pastoral, and juridical aspects. Moreover, other professors, while striving to expound the mystery of Christ and the history of salvation from the angle proper to each of their own subjects, must nevertheless do so in a way which will clearly bring out the connection between their subjects and the liturgy, as also the unity which underlies all priestly training. This consideration is especially important for professors of dogmatic, spiritual, and pastoral theology and for those of holy scripture.
