For wisdom opened the mouth of the dumb, and made the tongues of them that cannot speak eloquent.
Read Chapter 10
Fulgentius of Ruspe
AD 533
It is written that "wisdom opened the mouth of the mute and loosed the tongues of infants." Wisdom indeed opened the mouths of the mute, so the incredulous might believe, and loosed the tongues of infants, so that they might preach what they believed. Therefore, not without reason does Paul attribute his faith and his ability to speak to the gift of the Holy Spirit, saying, "Moved by that same spirit of faith of which it is written, "I believed, therefore I spoke," we also believe, and therefore we speak." A person believes with the will, and with the will speaks. The human will, however, cannot possess these things of its own if they are not given by God, "because wisdom opens the mouth of the mute and loosens the tongue of infants." - "On the Truth of Predestination 2.6.9"
If only I could sing like the choirs of angels! Oh, with what devotion I would pour myself out in your praises, reciting unceasingly and most excellently the hymn of your glory in the middle of the assembly! Will I perhaps keep silent because I cannot sing like them? Lord, woe to those who keep silent on your account, because "you open the mouth of the mute and loosen the tongue of infants." Since infants can only babble your praises, I ask you to accept the sacrifice from the tip of my tongue, from the love of my heart. - "Mirror 23"
