Some still appeal to the Bible in support of purgatory, but they appeal in vain. There is a famous passage in 2 Maccabees 12:39-45 where some who have died in battle are found to have been secret idolaters, whereupon Judas Maccabeus and his followers offer prayers and sacrifices on their behalf to make sure that they will come to share in the resurrection. This passage does indeed envisage an intermediate state: the resurrection has not yet happened, and some who (it was hoped) would attain it were found to have committed sin that had not yet been atoned for. But this isn't 'getting out of purgatory'; it's a matter of ensuring that, though all alike are in the intermediate state, those ones will rise again (not 'go to heaven', we note) to enjoy God's new world when it comes. The books of the Maccabees are, of course, in the Apocrypha; but the early Christians would in any case have replied that 'the blood of Jesus, God's son, cleanses us from all sin' (1 John 1.7). If any retrospective action were needed, it would be, at the most, baptism for those who had died unbaptised, though the single passage where that strange practice is mentioned (1 Corinthians 15:29) continues to be much disputed. Attempts to find other proof-texts are unconvincing at best and embarrassingly fanciful at worst.
