Typology is the study of how persons, events, and institutions in the Old Testament served as divinely ordained patterns that prefigured the work and person of Jesus Christ. While all Reformed traditions affirm the reality of these shadows, there is debate regarding how they function within the Covenant of Grace, with some traditions emphasizing continuity in signs and others emphasizing the distinction between the type and the substance found only in Christ.
In the Reformed tradition, a type is an exhibition of things expected, providing an imitative anticipation of the future. As noted in On the Holy Spirit Ch. 14 §31, the history of Israel and its ordinances—such as the exodus or the paschal lamb—were recorded to show forth the salvation later accomplished by Christ. These are not merely human inventions but are divinely intended shadows that point toward the reality of the gospel. As the Belgic Confession Art. 25 states, while the ceremonial shadows have ceased at the coming of Christ, their substance remains with us in Jesus, in whom they have their completion.

The danger in studying typology is to judge the reality by the shadow. We must remember that the types of the Old Testament were sufficient to build up the elect in faith in the promised Messiah, as noted in the Westminster Larger Catechism Q.34, yet they were always pointing away from themselves toward the Mediator. As On the Holy Spirit Ch. 14 §32 warns, comparing the typified reality with the type can sometimes lead people to disparage the gospel, failing to see that while the types were dreams or shadows, Christ is the substantial existence. We are reminded that we are more sinful than we dared believe, needing such grace, yet more loved in Christ than we dared hope, as He is the One to whom all the prophets bore witness.

The Old Testament points forward to Christ through promises, prophecies, and a system of types—such as sacrifices, the priesthood, and the kingdom—that were divinely ordained to instruct the elect and build their faith in the coming Messiah. While Reformed traditions hold that these shadows were efficacious through the Spirit to build faith, they emphasize that Christ is the sole substance and mediator, the reality to which all these temporary ceremonies pointed.
The Old Testament functioned as an administration of the same Covenant of Grace that we now enjoy, though it was veiled by ceremonies and types. According to the 1689 LBCF Ch.8 §6, the virtue, efficacy, and benefits of Christ’s redemption were communicated to the elect in all ages, even before His incarnation. The Westminster Confession of Faith Ch.7 §5 similarly teaches that these ordinances were sufficient and efficacious, through the operation of the Spirit, to build up the elect in faith in the promised Messiah. Thus, the Old Testament saints were not looking at empty rituals, but were looking through them to Christ, the Lamb slain from the foundation of the world.

The ceremonial and moral law functioned as a schoolmaster to guide the people of God toward the Mediator. As described in the Institutes of the Christian Religion Ch.7, these ceremonies were not mere toys, but formal symbols of confirmation pointing to the truth found only in Jesus. The Apostle Paul writes in Galatians 3:24: 'So that the law is become our tutor to bring us unto Christ, that we might be justified by faith.' This reveals that the gospel is not an afterthought; it is the very purpose for which the Old Testament was written. Without Christ, the law leaves us in despair, but through the lens of the gospel, we see that every sacrifice and prophet served to inflame the desire for the One who would truly take away sin.
