It is important to note that here Paul is giving Titus instructions on what to teach. It is important to declare the “whole counsel of God”, (cf. Acts 20:27). An aspect of that declaration is to teach every person, young or old, male or female, how they should direct their lives.
There are specific admonitions that different ages or genders need. This is not sexist or ageist, it is merely an acknowledgment of the order of life, and what God always requires of us. With this in mind, the text is a treasure trove of good instruction.
Older men are to be characterized by sobriety and reverence. The old women as well, and they are to teach the younger women with less experience. The younger women are to show love, deference and care to their husbands and children. The younger men are to be act with maturity. They are to have integrity and soundness in action.
Finally, bondservants are to serve their masters with fidelity as Christians should always do. The exhortations are simple, but needed. As too often they are ignored.
