The Epistula Titi, discipuli Pauli, de dispositione sanctimonii was discovered by D. De Bruyne in an 8th-c. W¼rzburg MS. Probably a sermon, it is an exhortation to chastity aimed at men and women and opposes the cohabitation of male ascetics with women vowed to virginity. Composed perhaps in a Priscillianist setting, it is disputed whether it was originally written in Latin or is a translation from the Greek, as De Bruyne prefers. The Latin and Priscillianist origin is defended by A. von Harnack and H. Koch, who hold that it uses Cyprian and the ps.-Cyprian De singularitate clericorum. G. Sfameni Gasparro, in an ample study, maintains rather that the anonymous author of the Epistula Titi is from a circle marked by rigoristic formulations of the enkrateia which are consistent with the definition of encratism, and which were attested also in the West in the 3rd and in the course of the 4th-5th c. Pointing out that the work shows close parallels to African works datable to the mid 4th c. at the latest, Sfameni Gasparro dates the Epistula to the late 4th c., in a generally Western context.
