Exploring the fluidity of divine-human boundaries in ancient Judaism, Daniel Lam challenges the assumption of a rigid divide between God and humanity. Drawing on prototype theory and texts from across millennia of Jewish and Christian literature, Lam argues that divinity was conceived as a graded category rather than an absolute state, suggesting that figures such as Adam, Enoch, Moses, Elijah, and Jesus were imagined as crossing the divine threshold through immortality, metamorphosis, and exaltation. By situating these traditions within their wider Mediterranean context, Lam reframes debates on monotheism, deification, and early Christology.

Lam engages deeply with primary sources, including Genesis and Psalms, Wisdom of Solomon, and the Life of Adam and Eve; Enochic writings such as the Book of the Watchers and Book of Parables; and New Testament passages like Philippians 2 and Hebrews 1. In addition, he examines lesser-known materials such as the Testament of Abraham, Qumran fragments, and 2 Enoch, highlighting motifs of angelomorphism, luminous transformation, and enthronement. These case studies illuminate how ancient authors negotiated divine identity and challenge the notion that divinisation was exclusively a "pagan" concept, offering a fresh methodological framework for understanding divinity as a fluid and multivalent phenomenon.
