And which is the result of a false premise to begin with, that being that a person is justified due to interior holiness, attained (usually) through infant sprinkling in recognition of proxy faith, and unless the infant dies before becoming morally accountable, then they (usually) need to go through an indeterminate time in the life beyond through fire and torments or 'purifying' punishments.” (INDULGENTIARUM DOCTRINA; cp. 1. 1967) in order to become good enough to enter Heaven. Salvation by grace through merit.
However, in Scripture God justifies the unGodly by faith, and while true faith is that which effects characteristic holiness in heart and deed, “things which accompany salvation,” (Heb. 6:9) and which includes repentance when one is convicted of sin, (1Jn. 1:6,9) yet one either has such faith, which has great recompense of reward, (Heb. 10:35) or he does not. And those professors who do not, but deny the faith as by drawing back in unbelief or impenitent sin, are not promised a second chance but damnation. (Gal. 5:1-4; Heb. 3:6,12,14; 10:25-39)
Those who are immature and do not always strive lawfully will suffer the grievous disapproval of the Lord and loss of rewards at His return (not at death), but will be saved despite the loss of works being burnt up, referring to what he built the church with, and not because of this loss. See 1Cor. 3 here. This is the only postmortem suffering for believers that is mentioned, and we are not to read into Scripture what is needed for support, or make what can only be speculative to be doctrine.
I am not going to refute these attempts to support Purgatory now, as i need to go out, but search what i wrote here and you should be able to see them dealt with.
Yet another convincing argument.
