Duty

Duty, in Scripture, is what God requires of human beings — a commanded loyalty of love, worship, and obedience directed toward God and toward the neighbor, rather than an impersonal moral obligation arrived at by human reasoning.

The text states the content of that requirement compactly in Deuteronomy 10:12, where Moses asks what Yahweh "requires" of Israel and answers: to fear him, walk in his ways, love him, and serve him with all the heart and soul. Deuteronomy 6:5 frames the same claim as whole-hearted love ("with all your heart, with all your soul, and with all your might"), and Leviticus 19:18 places love of neighbor alongside it ("you shall love your neighbor as yourself"). In Luke 10:27 a lawyer joins the two commands in a single answer, and Matthew 4:10 states the exclusive claim at the center of duty: "You shall worship the Lord your God, and you shall serve him only." Linguistically, the concept is carried in Scripture by verbs and nouns of requiring and commanding rather than by a single abstract term — Hebrew sha'al ("ask, require") in Deuteronomy 10:12, mitsvah ("commandment"), and 'avad ("serve"); Greek entolē ("commandment") and thelēma ("will") in the Gospels.

In the Gospels duty is regularly described as doing the will of God. Matthew 12:50 makes doing "the will of my Father who is in heaven" the mark of belonging to Jesus' family; John 4:34 presents Jesus himself as one whose "food is to do the will of him who sent me"; and John 15:14 ties friendship with him to doing what he commands, while John 14:21 identifies keeping his commandments with loving him. Matthew 25:34–46 gives duty a concrete and unsettling shape: the King's verdict turns on feeding, clothing, and visiting "one of the least of these," with the identification "you did it to me" (Matthew 25:40) and the outcome stated in Matthew 25:46.

Christian traditions differ in how they frame this. Catholic moral theology has classically distinguished binding precepts from counsels of perfection, treating certain duties as obligations for all and others as invitations to a fuller way. Protestant teaching, especially in Lutheran and Reformed streams, has stressed that obedience is the fruit of grace and gratitude rather than a means of merit, and has been wary of duty-language that sounds like earning favor. Some modern theologians prefer "discipleship" or "vocation" to "duty" for similar reasons. Readings of Matthew 25 also diverge: many take "the least of these" as the needy generally, while others read the phrase as referring specifically to Christian disciples or missionaries.
