Here is a short section from Jonathan Rainbow’s work The Will of God and The Cross: An Historical and Theological Study of John Calvin’s Doctrine of Limited Redemption.
The Universal Offer of the Gospel
Calvin clearly articulated a universal saving will of God that was conditional on faith, which consisted of the universal offer of the gospel through preaching … Calvin stressed that the gospel, and in it the benefits of Christ’s passion and death, are offered to all men. In such contexts Calvin made it clear that “all” means all men individually. Calvin the Latinist provided Calvin the theologian with a variety of terms to articulate this doctrine: the gospel is offered (offertur) to all, propounded (proponitur) to all, set forth (expositum esse) to all, and proclaimed (publicando) to all. These terms all denoted for Calvin the public preaching of the gospel through the agency of men. By this agency God invites (invitare) and calls (vocare) all men to salvation. That “all” means all individual men Calvin indicated by the adverbs indifferenter, promiscue, and sine exceptione which almost always occurred in such statements.
Calvin usually coupled his affirmations of this universal gospel offer with the reminder that only the elect actually receive the gospel. For the public offer of the gospel comes always with the demand for faith, and only the elect have faith. So Calvin saw God here operating in two circles of human beings, one the larger circle of all to whom the gospel is publically offered through preaching, and the other smaller circle of those who believe, the elect. This preached word is a kind of net cast into humanity at large which catches the elect and lets the reprobate slip back through. So there was in this sense in Calvin’s theology a “twofold will” of God. [C.f. commentaries on Ezek 18:23, 2 Pet 3:9, Matt 23:37.] … The universal offer of the gospel for Calvin was only and simply the public preaching of the gospel to all men; it was the will of God “which is manifested by the nature of the word, and is merely to invite by the outward voice of man.” If asked how such an offer can be made to every individual when God’s saving work and will do not extend to every individual, Calvin would not pretend to know. It is simply how God reveals himself.
******************
Now whilst Rainbow does not say everything that can be said in this short section he draws out a number of vital points:
- It is impossible to say the older reformed theologians ment only present/command by offer – look at the actual terms Calvin uses (including invite).
- For Calvin the gospel is a particular offer to every hearer.
- For Calvin it is possible to speak of the (revealed) will of God for the salvation of all.
- Calvin accepts the testimony of scripture and does not reject it because he cannot rationalise it i.e. he understands the finite cannot comprehend the infinite, that is the distinction between archetypal and ectypal theology.
