Islã segundo Mons. Lefebvre

Islam accepts Jesus as a prophet and has great respect for Mary, and this certainly places Islam nearer to our religion than say, for instance, Judaism, which is far more distant from us. Islam was born in the 7^th century and it has benefited to some degree from the Christian teachings of those days.

Judaism, on the other hand, is the heir to the system, which crucified our Lord. And the members of this religion, who have not converted to Christ, are those who are radically opposed to our Lord Jesus Christ. For them, there is no question whatever of recognizing our Lord.
