Mosaic Dietary Laws and Christological Fulfillment
The Mosaic dietary laws, detailed primarily in Leviticus 11 and Deuteronomy 14, distinguished clean from unclean animals for Israel's consumption. Among land animals, the law prohibited beasts of prey that devour other creatures in their blood; among water creatures, snake-like fishes and slimy shellfish; among birds, raptors and carrion-eaters [4]. These regulations formed part of the broader Mosaic legislation, which Easton's defines as "the whole body of the Mosaic legislation," a theocratic code referring "at once to the commandment of God as the foundation of all human duty" [1].
Christ's Subjection to the Law
Christ's fulfillment of these laws began with his subjection to them. Reformed theology articulates that "the humiliation of Christ included also his being made under the law," encompassing the Adamic covenant of works, the Mosaic law binding the chosen people, and the moral law as a rule of duty [2]. This subjection meant Christ assumed "the obligation to fulfil all righteousness, i.e., to do everything which the law in all its forms demanded" [2]. The dietary regulations, as part of the Mosaic covenant, fell within this comprehensive obedience.
Typological Fulfillment
The dietary laws functioned typologically, pointing beyond their immediate hygienic or symbolic purposes to spiritual realities. Tertullian and Origen recognized that "these rites were typical, and the truth was that which was to be taught them by the Holy Spirit" [5]. The entire sacrificial system, including its attendant purity regulations, was "designed to impress" God's justice and "to serve as prophetic types of the only effectual expiation which, in the fulness of time, was to be offered for the sins of men" [9]. Christ's death rendered these types obsolete by providing their substance.
The Transition in Acts and Romans
The early church's struggle with dietary observance appears in Romans 14, where Paul addresses Jewish believers who "adhered of conscience to the Law, and after their believing, still kept to the observance of meats" [3]. Chrysostom notes this pastoral tension between those who believed they could "eat all things" and those who, being "weak," ate only herbs [3]. The Jerusalem Council's silence on dietary restrictions for Gentile converts (beyond minimal requirements) signaled the ceremonial law's abrogation, though this silence parallels its treatment of other precepts whose obligation remained unquestioned [6].
Calvin observed that Christ's eternal priesthood, foretold in Psalm 110:4, necessitated abolishing the Levitical priesthood with its daily succession [8]. Since priesthood and dietary law were interwoven in the Mosaic economy, the former's dissolution entailed the latter's ceremonial obsolescence, even as the moral law's authority persisted [7].

- Easton's Bible Dictionary “Easton's Bible Dictionary: Law of Moses — Is the whole body of the Mosaic legislation (1 Kings 2:3; 2 Kings 23:25; Ezra 3:2). It is called by way of eminence simply "the Law" (Heb. Torah, Deut. 1:5; 4:8, 44; 17:18, 19; 27:3, 8). As a written code it is called the "book of the law of Moses" (2 Kings 14:6; Isa. 8:20), the "book of the law of God" (Josh. 24:26). The great leading principle of the Mosaic law is that it is essentially theocratic; i.e., it refers at once to the commandment of God as the foundation of all human duty.”
