John Calvin beautifully summarizes our duties in Christ in our several vocations:
Finally, let each one see to what extent he is in duty bound to others, and let him pay his debt faithfully.
For this reason let a people hold all its rulers in honour, patiently bearing their government, obeying their laws and commands, refusing nothing that can be borne without losing God’s favour [Rom. 13:1 ff.; 1 Peter 2:13ff.; Titus 3:1].
Again, let the rulers take care of their own common people, keep the public peace, protect the good, punish the evil. So let them manage all things as if they are about to render account of their services to God, the supreme Judge [cf. Deut. 17:19; 2 Chron. 19:6-7].
Let the ministers of churches faithfully attend to the ministry of the Word, not adulterating the teaching of salvation [cf. 2 Cor. 2:17], but delivering it pure and undefiled to God’s people. And let them instruct the people not only through teaching, but also through example of life. In short, let them exercise authority as good shepherds over their sheep [cf. 1 Tim. 3; 2 Tim. 2; 4; Titus 1:6ff.; 1 Peter 5].
Let the people in their turn receive them as messengers and apostles of God, render to them that honour of which the highest Master has deemed them worthy, and give them those things necessary for their livelihood [cf. Matt. 10:10ff.; Rom. 10:15 and 15:15ff.; 1 Cor. 9; Gal. 6:6; 1 Thess. 5:12; 1 Tim. 5:17-18].
Let parents undertake to nourish, govern, and teach, their children committed to them by God, not provoking their minds with cruelty or turning them against their parents [Eph. 6:4; Col. 3:21]; but cherishing and embracing their children with such gentleness and kindness as becomes their character as parents.
As we have already said, children owe obedience to their parents.
Let youth reverence old age, as the Lord has willed that age to be worthy of honour.
Also, let the aged guide the insufficiency of youth with their own wisdom and experience wherein they excel the younger, not railing harshly and loudly against them but tempering their severity with mildness and gentleness.
Let servants show themselves diligent and eager to obey their masters—not for the eye, but from the heart, as if they were serving God.
Also, let masters not conduct themselves peevishly and intractably toward their servants, oppressing them with undue rigor, or treating them abusively. Rather, let them recognize them as their brothers, their co-servants under the Lord of heaven, whom they ought to love mutually and treat humanely [cf. Eph. 6:5-9; Col. 3:22-25; Titus 2:9-10; 1 Peter 2:18-20; Col. 4:1; Philemon 16].
In this manner, I say, let each man consider what, in his rank and station, he owes to his neighbours, and pay what he owes. Moreover, our mind must always have regard for the Lawgiver, that we may know that this rule was established for our hearts as well as for our hands, in order that men may strive to protect and promote the well-being and interests of others. (Institutes of the Christian Religion, II.viii.46)
