What an ignorant question. You must be a Protestant.
And every man shall receive his own reward, according to his own labour. [9] For we are God's coadjutors: you are God's husbandry; you are God's building. [10] According to the grace of God that is given to me, as a wise architect, I have laid the foundation; and another buildeth thereon. But let every man take heed how he buildeth thereupon. [11] For other foundation no man can lay, but that which is laid; which is Christ Jesus. [12] Now if any man build upon this foundation, gold, silver, precious stones, wood, hay, stubble: [13] Every man's work shall be manifest; for the day of the Lord shall declare it, because it shall be revealed in fire; and the fire shall try every man's work, of what sort it is. [14] If any man's work abide, which he hath built thereupon, he shall receive a reward. [15] If any man's work burn, he shall suffer loss; but he himself shall be saved, yet so as by fire. (1 Cor. 3)
Are you saying that Paul laid the foundation for purgatory, annalex? He clearly states that he laid the foundation according to the grace of God that was given him. Wouldn’t that make him of greater importance to the Catholic Church than Peter?
