Whether this punishment is voluntary?
Objections
❌ Objection 1 : It would seem that this punishment is voluntary. For those who are in Purgatory are upright in heart. Now uprightness in heart is to conform one's will to God's, as Augustine says (Serm. i in Ps. 32). Therefore, since it is God's will that they be punished, they will suffer that punishment voluntarily.
❌ Objection 2 : Further, every wise man wills that without which he cannot obtain the end he has in view. Now those who are in Purgatory know that they cannot obtain glory, unless they be punished first. Therefore they are punished willingly.
