St. Ambrose...
This wonderful quote from my friend Pastor Craig Satterlee of LSTC: "You went [to the font], you washed, you came to the altar, you began to see. That is to say, through the font of the Lord and the preaching of the Lord’s passion, at that moment your eyes were opened. Before, you seemed to be blind of heart. But now you began to perceive the light of the sacraments." Ambrose, De sacramentis 3.2.15 (SC 25bis.100).
