The perfection God requires has been achieved for us by Jesus Christ. It is HIS righteousness not ours, we need to do nothing to attain it other than to believe and confess Him as Lord. Purgatory is not necessary and the concept is an insult to the finished work of Christ that will be revealed in us at His coming. Christ’s sacrifice on our part was sufficient and complete, nothing needs to be added.
We need to do our part, too. Perhaps we didn’t pay full reparation for some misdeed on earth. That’s why Catholics have Purgatory instead of hell.
And I don’t think Catholics are the only ones that need to make up that reparation.
Amen.
