Matthew 9:30

And Jesus strictly charged them. Although our Saviour strictly charged them to keep the miracle silent, they nevertheless published it throughout all that country; not being able to contain themselves, they became the evangelists and publishers of what they were commanded to conceal. Thus we are admonished not only to keep silent ourselves whatever is to our own commendation, but likewise to endeavour to hinder others from publishing it; to act otherwise would be to render ourselves odious to men, and abominable in the sight of God. But if we are silent, we shall obtain greater glory in the sight both of God and men. On the other hand, whatever redounds to the glory of the Almighty, we must ourselves publish, and exhort others to make it known to the whole world. Therefore it is said, Go and relate the glory of God. (St. John Chrysostom, hom. xxxiii.)
