Some Protestant readers have alleged that the Catholic Church teaches a certain form of universalism or relativism and they quote paragraph #841 of the Catechism of the Catholic Church in order to prove it:
841 The Church's relationship with the Muslims. "The plan of salvation also includes those who acknowledge the Creator, in the first place amongst whom are the Muslims; these profess to hold the faith of Abraham, and together with us they adore the one, merciful God, mankind's judge on the last day."
A few observations. The plan of salvation includes Muslims. This is common sense. God desires all men to be saved. This does not mean that Muslims are saved by virtue of their being Muslims. This passage should be read in context of the entire Catechism which teaches that salvation is received through Christ alone through the means of grace provided through the Church of Jesus Christ. One cannot wrench this paragraph from the catechism and let it stand alone.
One could easily take certain passages out of the writings of St. Paul and make false assumptions that Paul was a universalist. For example: St Paul teaches universalism because he wrote:
"Then as one man's trespass led to condemnation for all men, so one man's act of righteousness leads to acquittal and life for all men." (Rom 5:18)This is a misguided argument because one must read the verse above in light of all the writings of St. Paul. In the same way, one cannot isolate paragraph 841 from the rest of the Catechism.
The Church recognizes that the object of worship in Islam is the God of Abraham and thus the one true God. Thus, we might say that Muslims worship the true God wrongly. They attempt to find access to God in a means that is not sacrificial, and worse, not Christological. It is like men trying to hunt deer with a slingshot. They are technically "hunting deer" but their method is never going to put venison on the table. Alternatively, it is like a baseball pitcher trying to strike out a batter. He's aiming for the strike-zone, but he's throwing a feather. He had the right target but the wrong approach. The strikeout will never happen until he conforms to the established rules...and proper means.
