Moral Law as an Expression of God's Love
The concept of the moral law as an expression of God's love is rooted in biblical teachings and has been explored by various Christian traditions. The biblical anchor for this idea is found in passages such as Romans 13:10, which states that "love is the fulfillment of the law" [3]. This notion is reinforced by Jesus' teaching that the second great commandment is to "love your neighbor as yourself" (Matthew 22:39), and that loving God is equivalent to keeping His commandments (1 John 5:3) [1, 4].
In the view of many Christian traditions, the moral law is not merely a set of rules but an expression of God's character and love. According to John Calvin, the law is a reflection of God's righteousness and justice [5]. The moral law, as part of the Old Law, contains precepts that are moral, ceremonial, and judicial. Thomas Aquinas argues that the moral precepts of the Old Law are universal and unchanging, reflecting the natural law that is written on human hearts [11].
The relationship between love and law is a central theme in Christian theology. The Apostle Paul writes that "love doesn't harm a neighbor. Love therefore is the fulfillment of the law" (Romans 13:10) [3]. This idea is echoed in the writings of John, who states that "love is the keeping of his laws" (2 John 1:6) [2]. According to Jamieson, Fausset & Brown, this commandment to love is the sum of all God's other commandments [6].
Different Christian traditions have nuanced understandings of the moral law. The Reformed tradition, as represented by John Calvin and Charles Hodge, emphasizes the law as a reflection of God's holiness and justice [5, 7]. In contrast, the Methodist/Wesleyan tradition, as represented by Adam Clarke, views the law as a means of promoting holiness and love [8, 9]. The Catholic tradition, following Thomas Aquinas, sees the moral law as an expression of natural law and a participation in God's eternal law [11].
The Jewish tradition, as represented by the Babylonian Talmud, also understands the law as an expression of God's will, but with a focus on the specific commandments and their interpretation [10].

The preeminence of this commandment is further evident from the fact that religion, or the duty we owe to God, is the foundation of morality. Without the former, the latter cannot exist. This is plain, (1.) From the nature of the case. Morality is the conformity of an agent’s character and conduct to”

I answer that, The Old Law contained some moral precepts; as is evident from Ex. 20:13,15: "Thou shalt not kill, Thou shalt not steal." This was reasonable: because, just as the principal intention of human law is to created friendship between man and man; so the chief intention of the Divine law is to establish man in friendship with God.
