Alcuin of York — as excerpted in the Catena Aurea on John 14:1-4

“He says then, If I go, by the absence of the flesh, I shall come again, by the presence of the Godhead; or, I shall come again to judge the quick and dead. And as He knew that they would ask whither He went, or by what way He went, He adds, And whither I go ye know, i. e. to the Father, and the way ye know, i. e. Myself.”
