John Calvin's Commentary on the Bible

18 (Romans 8:18)

Verse 18

18.I indeed judge, (258) etc. Though they take not altogether an unsuitable view who understand this as a kind of modification; yet I prefer to regard it in the light of an encouragement, for the purpose of anticipating an objection, according to this import, β€” β€œIt ought not indeed to be grievous to us, if we must pass through various afflictions into celestial glory, since these, when compared with the greatness of that glory, are of the least moment.” He has mentioned future for eternal glory, intimating that the afflictions of the world are such as pass away quickly.

It is hence evident how ill understood has this passage been by the Schoolmen; for they have drawn from it their frivolous distinction between congruity and condignity. The Apostle indeed compares not the worthiness of the one with that of the other, but only lightens the heaviness of the cross by a comparison with the greatness of glory, in order to confirm the minds of the faithful in patience.
