54.  What of the laboriousness of his teaching?  The manifold character of his ministry?  His loving kindness?  And on the other hand his strictness?  And the combination and blending of the two; in such wise that his gentleness should not enervate, nor his severity exasperate?  He gives laws for slaves and masters, Eph. vi. 5, 9. rulers and ruled, Rom. xiii. 1–3. husbands and wives, Eph. v. 25, 22. parents and children, Eph. vi. 1–4. marriage and celibacy, 1 Cor. vii. 3, 8, 25, 31. self-discipline and indulgence, Rom. xiv. 3, 6. wisdom and ignorance, 1 Cor. i. 27; iii. 18. circumcision and uncircumcision, Rom. ii. 25, 29. Christ and the world, the flesh and the spirit. Gal. v. 16.  On behalf of some he gives thanks, others he upbraids.  Some he names his joy and crown, Phil. iv. 1. others he charges with folly. Gal. iii. 1.  Some who hold a straight course he accompanies, sharing in their zeal; others he checks, who are going wrong.  At one time he excommunicates, 1 Cor. v. 5. at another he confirms his love; 2 Cor. ii. 8. at one time he grieves, at another rejoices; at one time he feeds with milk, at another he handles mysteries; 1 Cor. ii. 7; iii. 2. at one time he condescends, at another he raises to his own level; at one time he threatens a rod, Ib. iv. 21. at another he offers the spirit of meekness; at one time he is haughty toward the lofty, at another lowly toward the lowly.  Now he is least of the apostles, Ib. xv. 9. now he offers a proof of Christ speaking in him; 2 Cor. xiii. 3. now he longs for departure and is being poured forth as a libation, Phil. i. 23; ii. 17. now he thinks it more necessary for their sakes to abide in the flesh.  For he seeks not his own interests, but those of his children, 1 Cor. x. 33. whom he has begotten in Christ by the gospel. Ib. iv. 15.  This is the aim of all his spiritual authority, in everything to neglect his own in comparison with the advantage of others.
