Today’s Office of Readings at divineoffice.org excerpt from a treatise on the Gospel of Saint Matthew by Saint Chromatius, bishop:
If we fail to live in the light, we shall, to our condemnation and that of others, be veiling over and obscuring by our infidelity the light men so desperately need. As we know from Scripture, the man who received the talent should have made it produce a heavenly profit, but instead he preferred to hide it away rather than put it to work and was punished as he deserved.
Consequently, that brilliant lamp which was lit for the sake of our salvation should always shine in us. For we have the lamp of the heavenly commandment and spiritual grace, to which David referred: Your law is a lamp to my feet and a light to my path. Solomon also says this about it: For the command of the law is a lamp.
Therefore, we must not hide this lamp of law and faith. Rather, we must set it up in the Church, as on a lamp-stand, for the salvation of many, so that we may enjoy the light of truth itself and all believers may be enlightened.
