St Catherine of Genoa
edit
On the cusp of the Reformation, St Catherine of Genoa (1447–1510) re-framed the theology of purgatory as voluntary, loving and even joyful:
"As for paradise, God has placed no doors there. Whoever wishes to enter, does so. An all-merciful God stands there with His arms open, waiting to receive us into His glory. I also see, however, that the divine presence is so pure and light-filled – much more than we can imagine – that the soul that has but the slightest imperfection would rather throw itself into a thousand hells than appear thus before the divine presence."[47]
So purgatory is a state of both joy and voluntary pain:
Again the soul perceives the grievousness of being held back from seeing the divine light; the soul’s instinct too, being drawn by that uniting look, craves to be unhindered”
