Augustine of Hippo
Catena Aurea · Matthäusevangelium 5
Blessed are ye, when men shall revile you, and persecute you, and shall say all manner of evil against you falsely, for My sake. Rejoice, and be exceeding glad: for great is your reward in heaven: for so persecuted they the prophets which were before you.
(Serm. in Mont. i. 5.) Do not suppose that by heaven here is meant the upper regions of the sky of this visible world, for your reward is not to be placed in things that are seen, but by in heaven understand the spiritual firmament, where everlasting righteousness dwells. Those then whose joy is in things spiritual will even here have some foretaste of that reward; but it will be made perfect in every part when this mortal shall have put on immortality.
