You ask that if there is Temporal punishment then what did our Lord suffer and die for, I would say that he has saved us from eternal punishment.
Here is the main scriptural basis for the western concept of Purgatory, especially verse 15 “But if someone’s work is burned up, that one will suffer loss; the person will be saved, but only as through fire.” A better way to say it is that Purgatory is the western name for what St Paul is talking about in these verses. While is popular conception this has been talked about as a place, most contemporary western Catholic theologians would say that this is a process or a state of being. The soul is saved but is still short of it’s final eternal heavenly destiny.
Just to show that this interpretation is consistent with the Fathers, I will cite the
Catholic Encyclopedia:
"While this passage presents considerable difficulty, it is regarded by many of the Fathers and theologians as evidence for the existence of an intermediate state in which the dross of lighter transgressions will be burnt away, and the soul thus purified will be saved. This, according to Bellarmine (De Purg., I, 5), is the interpretation commonly given by the Fathers and theologians; and he cites to this effect:
St. Ambrose (commentary on the text, and Sermo xx in Ps. cxvii),
St. Jerome, (Comm. in Amos, c. iv),
St. Augustine (Enarration on Psalm 37),
St. Gregory (Dial., IV, xxxix), and
Origen (Hom. vi in Exod.)."

Also, we read in the Jewish Encyclopedia, showing continuity:
"The view of purgatory is still more clearly expressed in rabbinical passages, as in the teaching of the Shammaites: ‘In the last judgment day there shall be three classes of souls: the righteous shall at once be written down for the life everlasting; the wicked, for Gehenna; but those whose virtues and sins counterbalance one another shall go down to Gehenna and float up and down until they rise purified; for of them it is said: ‘I will bring the third part into the fire and refine them as silver is refined, and try them as gold is tried’ [Zech. xiii. 9.]; also, ‘He [the Lord] bringeth down to Sheol and bringeth up again’’ (I Sam. ii. 6). The Hillelites seem to have had no purgatory; for they said: ‘He who is ‘plenteous in mercy’ [Ex. xxxiv. 6.] inclines the balance toward mercy, and consequently the intermediates do not descend into Gehenna’ (Tosef., Sanh. xiii. 3; R. H. 16b; Bacher, “Ag. Tan.” i. 18). Still they also speak of an intermediate state.
Regarding the time which purgatory lasts, the accepted opinion of R. Akiba is twelve months; according to R. Johanan b. Nuri, it is only forty-nine days. Both opinions are based upon Isa. lxvi. 23-24: ‘From one new moon to another and from one Sabbath to another shall all flesh come to worship before Me, and they shall go forth and look upon the carcasses of the men that have transgressed against Me; for their worm shall not die, neither shall their fire be quenched"; the former interpreting the words “from one new moon to another” to signify all the months of a year; the latter interpreting the words "from one Sabbath to another,’ in accordance with Lev. xxiii. 15-16, to signify seven weeks. During the twelve months, declares the baraita (Tosef., Sanh. xiii. 4-5; R. H. 16b), the souls of the wicked are judged, and after these twelve months are over they are consumed and transformed into ashes under the feet of the righteous (according to Mal. iii. 21 [A. V. iv. 3]), whereas the great seducers and blasphemers are to undergo eternal tortures in Gehenna without cessation (according to Isa. lxvi. 24).
The righteous, however, and, according to some, also the sinners among the people of Israel for whom Abraham intercedes because they bear the Abrahamic sign of the covenant are not harmed by the fire of Gehenna even when they are required to pass through the intermediate state of purgatory ('Er. 19b; Ḥag. 27a)."
