Doctor of Sacred Theology

The Doctor of Sacred Theology (S.T.D. Sacrae Theologiae Doctor) is the final theological degree in the pontifical university system of the Catholic Church.

The degree builds upon the work of the Bachelor of Sacred Theology (S.T.B.) and the Licentiate of Sacred Theology (S.T.L.). Normally, the S.T.B. is earned in three years, provided the candidate has at least two years of undergraduate study of philosophy before entering an S.T.B. program (if not, the S.T.B. will take five years; Sapientia Christiana assumes this to be the normal situation). The S.T.L. is normally earned in an additional two years, and the S.T.D. is earned after the writing, defense and publication of the doctoral dissertation (an additional 2–3 years). At institutions that offer both civil and church doctorates, the requirements of the S.T.D. will usually—although not always—be shaped so that those reading for the award can receive a Th.D. or Ph.D. in the process of meeting the requirements of the S.T.D.

This compares with, for example in North American institutions, the four-year program for a B.A. at many universities, a two-year program for an M.A., and the writing and successful defense of the doctoral dissertation for the Ph.D. or Th.D. (an additional 2–3 years).

A sketch of the degree cycle and requirements for ecclesiastical degrees can be found in John Paul II's apostolic constitution, Sapientia Christiana.
