Sidney Machado, of the Faculdades Claretianas in Brazil, and visiting professor at the Pontifical Ateneo Santo Anselmo in Rome, has added to the extensive literature on 1 Timothy 3:16 with a recent article in Revista Pistis Praxis.

The article is in Portuguese, but the abstract in English will provide guidance:

Abstract: The theme of epiphany/vision unifies most religious and philosophical expressions in the early Greco-Roman world. The use of the expression “manifested in the flesh” (“ἐφανερωθη ἐν σαρκί” (1Tm 3,16)) in the Pastoral Letters [is indicative] of the efforts of early Christianity to dialogue with the culture and inculturate the content of the Christian faith in the Hellenistic environment. Seeing the commitment to inculturated evangelization in the early Church constitutes an incentive and a provocation in view of an inculturated evangelization.
