If God demands ultimate love, what of other loves? The love of neighbour can further be divided into love for Christian brethren (John 13:34), love for family (Eph. 5:22–6:4), love for non-Christian neighbour (Rom. 13:9–10; Gal. 6:10) and love for enemy (Rom. 12:18–20; Matt. 5:4). The fact that love of neighbour is bundled together with love for God implies that the Second Commandment is an application of the First. That is, neighbours are to be loved for God’s sake.
Is the idea of correspondent, or ordinate, love present in Scripture? Does Scripture describe what love for God should be? It does indeed. In terms of degree, Scripture makes a hierarchy of loves very clear. The first of the Ten Commandments is “You shall have no other gods before me” (Exod. 20:3). Deuteronomy 6:4–5 was the positive wording of the same commandment. In conversation with a scribe, Jesus explained that the command of Deuteronomy 6:4-5 was the ultimate obligation, followed by a second: Jesus answered him, ‘The first of all the commandments is: ‘Hear, O Israel, the LORD our God, the LORD is one. And you shall love the LORD your God with all your heart, with all your soul, with all your mind, and with all your strength.’ This is the first commandment. And the second, like it, is this: ‘You shall love your neighbour as yourself.’ There is no other commandment greater than these’ (Mark 12:29–31).
It appears that Christ was interpreting the Shema to mean that the uniqueness of God demanded an answering form of ultimate love. This statement by Christ can be stated as the first of three biblical definitions of correspondent love.
1) Correspondent love for God loves God ultimately, and all else for his sake. Only God is to be loved wholeheartedly, which is to say, loved ultimately, as the only God. A god is one in whom a person places ultimate trust and looks to it for ultimate delight. Gods are found at the end of one’s chains of value and are not loved as a means to another love (that is, instrumentally), but are loved for themselves (that is, ultimately). God alone is to be loved as an end, and not as a means, for no one else is the true God. God alone deserves to be loved for himself; all other loves should be instrumental to that end (Ps. 73:25–26).
