Canon III.
Canons of Local Councils Received Ecumenically (Ancyra, Gangra, Neocaesarea, Antioch, Laodicea) · The Seven Holy Ecumenical Councils
If any one shall teach a slave, under pretext of piety, to despise his master and to run away from his service, and not to serve his own master with good-will and all honour, let him be anathema.
LocalE 3.6.2
This canon is framed in accordance with the doctrine of the Apostle, in I. Timothy, chapter six, verse 1. “Let as many servants as are under the yoke count their own masters worthy of all honour, that the name of God and his doctrine be not blasphemed.” And again the same Apostle teaches his disciple Titus that he should “exhort servants to be obedient unto their own masters, and to please them well in all things; not answering again; not purloining, but shewing all good fidelity; that they may adorn the doctrine of God our Saviour in all things.” (Titus ii. 9 and 10.)
