We were wondering about something; Does everyone (who doesn’t make it to Heaven or doomed to Hell) go to purgatory or is it a place only for Catholics? Do Protestants who don’t believe in it or Buddhists, etc. still go there? And if so, are their eyes opened to the truth when they get there or are they still confused about what really happens after death?
Purgatory is not really a place but a state of being, if anything it is the queue line outside the Pearly Gates where we are purged of our attachment to sin.
We don’t work our way out, it is through God and Prayers of the church that we are Purged.
There are no second chances after death, so undoubtedly everyone will know the truth , but you will no longer be able to choose God if you rejected Him in life.
Pope John Paul II summed it up well as follows,
Every trace of attachment to evil must be eliminated, every imperfection of the soul corrected. Purification must be complete, and indeed this is precisely what is meant by the Church’s teaching on purgatory. The term does not indicate a place, but a condition of existence. Those who, after death, exist in a state of purification, are already in the love of Christ who removes from them the remnants of imperfection (cf. Ecumenical Council of Florence, Decretum pro Graecis: DS 1304; Ecumenical Council of Trent, Decretum de iustificatione: DS 1580; Decretum de purgatorio: DS 1820).
It is necessary to explain that the state of purification is not a prolungation of the earthly condition, almost as if after death one were given another possibility to change one’s destiny. The Church’s teaching in this regard is unequivocal and was reaffirmed by the Second Vatican Council which teaches: "Since we know neither the day nor the hour, we should follow the advice of the Lord and watch constantly so that, when the single course of our earthly life is completed (cf. Heb 9: 27), we may merit to enter with him into the marriage feast and be numbered among the blessed, and not, like the wicked and slothful servants, be ordered to depart into the eternal fire, into the outer darkness where “men will weep and gnash their teeth’ (Mt 22: 13 and 25: 30)” (Lumen gentium, n. 48).
