<p>2:1 <i>But you</i>- Despite the presence of other, false, teachers, Titus was to focus on teaching which promoted spiritual health or 'soundness'.</p><p><i>Must teach what accords with sound doctrine- </i>His teaching was to accord with sound teaching; presumably referring to the basic teachings which comprised the Gospel message. The argument suggests that &ldquo;sound doctrine&rdquo; is a body of material against which subsequent teaching can be compared.Being unsound in the Faith is another way of saying that in works a man is denying Christ; to be &quot;sound in the faith&quot; is to tell the truth and not be lazy nor gluttonous (Tit. 1:13,16). Good behaviour &quot;adorns the doctrine of God&quot;, i.e. the basic doctrines of the Gospel (Tit. 2:10); the practical commandments of Tit. 2:2-10 are &quot;the things which befit the sound doctrine&quot; (Tit. 2:1 RV) which Titus was to teach. It's almost as if Paul is telling Titus to bring out the practical implications of the doctrines which he was teaching. &ldquo;Doctrine&quot; refers to a code of behaviour, not just a set of correct propositions concerning God and His plan with men. Thus we don't read about &quot;<i>pure</i> doctrine&quot; anywhere in the AV; but rather &quot;<i>sound</i> doctrine&quot;: living, active doctrine. The things which become sound doctrine are soberness, etc. (Tit. 2:1-4).</p>
