Enter by the narrow gate. For the gate is wide and the way is easy that leads to destruction, and those who enter by it are many. For the gate is narrow and the way is hard that leads to life, and those who find it are few.
So Jesus again said to them, "Truly, truly, I say to you, I am the door of the sheep. All who came before me are thieves and robbers, but the sheep did not listen to them. 9I am the door. If anyone enters by me, he will be saved and will go in and out and find pasture. The thief comes only to steal and kill and destroy. I came that they may have life and have it abundantly. I am the good shepherd. The good shepherd lays down his life for the sheep.
That's kind of the whole point of this section of the catechism. Christians, by virtue of our understanding of Christ and His Revelation have a more advantageous position regarding salvation than say a animist in some remote jungle. Conversely, the Jews enjoy a special relationship with the Lord which can never be supplanted by any other people. The Muslims, by virtue of their adherence to monotheism are more progressed theologically, than say a polytheist in Bangladesh.
The Church doesn't say "Muslims are in first place over the Jews" it says that in some way, God has called out to a people other than those called in the OT and NT. Imperfect as it may be, and it is highly defective, the Muslims believe that they believe in the same God as Abraham did. That's a start, and from there we trust that God has a plan for these people.
AMEN!
