The Venerable Bede, one of the great Saints of the Church, once said: “In the performance of [a miracle of healing] Jesus requested silence. Yet it did not remain concealed in silence for long. So it is with the called people of God — while following his precepts and example, they may prefer their responsible actions to remain unspoken, yet for the benefit to others providence may allow them to become known contrary to their own wishes.” (Bede, Homilies of the Gospels, 1.10)
We too don’t draw attention to our good deeds necessarily, but the Holy Spirit may see to it that people know — or don’t know. In either event, whatever we do, we do as the Lord permits, for the glory of the Lord and for the welfare of our sisters and brothers in Christ.
