Christian theology has always granted the body some role in saving rite, but few traditions lift it to the soteriological dignity it bears in Latter-day Saint ordinance theology. This paper argues, through constructive theological engagement with phenomenology and comparative sacramental thought, that Latter-day Saint praxis offers an account in which the body functions neither as instrument of grace nor as its symbol, but as the medium of covenantal mediation itself. Chrétien (2004), following Aristotle (De Anima II.2), argues that touch is “the most fundamental and universal of all senses” — “the first attestation of the soul” (p. 85). Fuchs (2023) shows touch alone cannot be virtualized; Wirzba (2008) theologizes the insight, naming touch the medium through which covenantal relation is realized in Christ, “the archetype of all relation.” Latter-day Saint theology radicalizes this consensus through a distinctive Christian materialism (Givens, 2014; Webb, 2012) in which “the spirit and the body are the soul of man” (D&C 88:15) and divine embodiment is affirmed (D&C 130:22). Within this ontology, ordinance praxis — baptism, confirmation, priesthood blessings, temple rites — is constitutively tactile. Proxy work most starkly reveals touch as enacted covenant: the living body becomes the indispensable medium through which saving ordinances are extended to the dead, contributing to what Joseph Smith called the “welding link” of generations and dispensations (D&C 128:18). The account intervenes in contemporary sacramental debate and grounds principled theological resistance to the digital substitution of ordinance.
