What about the custom of feeding the newly baptized a mixture of milk and honey?

The answer

St. Cyril of Jerusalem does not mention the custom that Bingham¹³⁷⁹ describes, of the newly baptized greeting one another with a holy kiss and eating a mixture of milk and honey after they emerge from the baptismal water. Tertullian¹³⁸⁰ mentions the custom of eating milk and honey. Perhaps drinking milk symbolized the pure and incorruptible teaching that the Church gives to her children through her faith, rites, and worship. Honey symbolizes Christ’s commandments that are sweet in His children’s mouths as they are sweeter than honey and the honeycomb.
