Augustine of Hippo, on John 20:19

“Now when it was late that same day, the first of the week, and the doors were shut, where the disciples were gathered together, for fear of the Jews, Jesus came and stood in the midst, and said to them: Peace be to you.”

“(de Civ. Dei.) The glory, wherewith the righteous shall shine like the sun in the kingdom of their Father, i. e. in Christ’s body, we must believe to have been rather veiled than not to have been there at all. He accommodated His presence to man’s weak sight, and presented Himself in such form, as that His disciple could look at and recognise Him.”
