Final answer:
St. Hilary's tactics for re-educating the Semi-Arians involved robust theological arguments and the strategic use of language, paralleling familiar concepts from other religious traditions, within the broader context of early Christian theological debates and practices.
Step-by-step explanation:
The question refers to the tactics used by St. Hilary in his efforts to re-educate the Semi-Arians concerning the true nature of Jesus. This is primarily a historical inquiry related to early Christian theology and the controversies surrounding the nature of Jesus in relation to the Father, which was a significant issue in the early Church. St. Hilary of Poitiers, a prominent fourth-century bishop and theologian, played a crucial role in opposing Arianism, which argued that the Son of God was not co-eternal with the Father and was instead a creature made by God. While the provided text does not directly address St. Hilary's methods, it discusses the broader context of early Christian theological debates, influences from other religious traditions, and the transformation of certain practices from secret Mysteries to public teachings within early Christianity. The key practices associated with re-education during this time often involved robust theological arguments, biblical exegesis, and the strategic use of language that might appeal to the beliefs of those being instructed, drawing parallels with familiar concepts from other religious traditions when beneficial.
