Thomas Aquinas,
Summa Theologiae — Question 89 - OF THOSE WHO WILL JUDGE AND OF THOSE WHO WILL BE JUDGED AT THE GENERAL JUDGMENT…
“ I answer that, The judicial power was bestowed on Christ as man, in reward for the humility which He showed forth in His passion. Now in His passion He shed His blood for all in point of sufficiency, although through meeting with an obstacle in some, it had not its effect in all. Therefore it is fitting that all men should assemble at the judgment, to see His exaltation in His human nature, in respect of which "He was appointed by God to be judge of the living and of the dead." ”
