Gregory of Nazianzus, on Exod 12:22

“And dip a bunch of hyssop in the blood that is at the door, and sprinkle the transom of the door therewith, and both the door cheeks: let none of you go out of the door of his house till morning.”

“Be it so, some will say, in the case of those who ask for baptism; what have you to say about those who are still children and conscious neither of the loss nor of the grace? Are we to baptize them too? Certainly, if any danger presses. For it is better that they should be unconsciously sanctified than that they should depart unsealed and uninitiated.A proof of this is found in the circumcision on the eighth day, which was a sort of typical seal. It was conferred on children before they had use of reason. And so is the anointing of the doorposts, which preserved the firstborn, though applied to things which had no consciousness.”
