This article defends Thomas Aquinas’s doctrine that Christ’s humanity is an instrument of the divinity (instrumentum divinitatis). This doctrine arises from biblical teaching that God saves us in Christ’s human actions and sufferings. Scripture raises the question of how God saves by human actions. This article argues that Aquinas’s ‘instrument doctrine’ answers this question. It expounds the doctrine, which is constituted in five propositional-paragraphs drawn from Aquinas’s mature Christology, and contrasts it with another model of how Christ saves. Then it responds to two major objections to the doctrine. It concludes with two theological entailments for Christology.

Logos 的肉体，Instrumentum divinitatis：检索古老的基督教教义

这篇文章为托马斯·阿奎那的教义辩护，即基督的人性是神性的工具（instrumentum divinitatis）。这一教义源于圣经教导，即上帝在基督的人类行为和苦难中拯救了我们。圣经提出了上帝如何通过人类行为来拯救的问题。本文认为，阿奎那的“工具学说”回答了这个问题。它阐述了由阿奎那成熟的基督论中的五个命题段落构成的教义，并将其与基督如何拯救的另一种模式进行了对比。然后它回应了对该学说的两个主要反对意见。它以基督论的两个神学蕴涵作为结束。
