[dangus]

Justification is instantaneous. Souls in purgatory are bound for Heaven; they have been justified. They need to be sanctified. Sanctified and justified are not synonyms.

[wolfman]

Purgatory is not only unnecessary, but it contradicts God’s word. Purgatory implies that a person must atone for his own sins. It implies that the person must do more than what the Law of God requires of him. This is called supererogation.
