The statement in question has disturbed me, too. I have the same opinion of Islam, that it came along to specifically deny the Crucifixion of Christ, the Sonship and Deity of Christ, and to proclaim Mohammed as the “Paraclete.” Amongst heresies it is the chief, it goes even beyond heresy, building on Manichaeism to become, in my opinion, the “spirit of antichrist” that denies that Christ is come in the flesh.
That said, I came into the Catholic Church a couple of years ago. I did this because the Church has the fullness of the faith, and because her wisdom of 2000 years is an ocean compared to my shallow pool of understanding. I have had to overcome a lot, to swallow my pride in a lot of areas, to acknowledge that the Church has the authority given her by Christ Himself. Too often I see Catholics and former Catholics who are overwhelmed by some pressure they feel in the world to turn on the Church. We are all oppressed today by Islam and its rampant violent chaos. How dare the Church proffer even a gesture of solidarity with the humanity of these devils? I think, however, a sober reading of Lumen Gentium is in order. Let’s see where the emphasis really is.
"14. This Sacred Council wishes to turn its attention firstly to the Catholic faithful. Basing itself upon Sacred Scripture and Tradition,
it teaches that the Church, now sojourning on earth as an exile, is necessary for salvation.
Christ, present to us in His Body, which is the Church, is the one Mediator and the unique way of salvation. In explicit terms He Himself affirmed the necessity of faith and baptism(124) and thereby affirmed also the necessity of the Church, for through baptism as through a door men enter the Church.
Whosoever, therefore, knowing that the Catholic Church was made necessary by Christ, would refuse to enter or to remain in it, could not be saved.
…
15. The Church recognizes that in many ways she
is linked with those who, being baptized, are honored with the name of Christian,
though they do not profess the faith in its entirety or do not preserve unity of communion with the successor of Peter. (14*) For there are many who honor Sacred Scripture, taking it as a norm of belief and a pattern of life, and who show a sincere zeal. They lovingly believe in God the Father Almighty and in Christ, the Son of God and Saviour. (15*) They are consecrated by baptism, in which they are united with Christ.
…
Likewise we can say that in some real way they are joined with us in the Holy Spirit, for to them too He gives His gifts and graces whereby He is operative among them with His sanctifying power. Some indeed He has strengthened to the extent of the shedding of their blood. *
In all of Christ’s disciples the Spirit arouses the desire to be peacefully united, in the manner determined by Christ, as one flock under one shepherd, and He prompts them to pursue this end. (17) Mother Church never ceases to pray, hope and work that this may come about. **She exhorts her children to purification and renewal so that the sign of Christ may shine more brightly over the face of the earth.
- Finally, those who have not yet received the Gospel are related in various ways to the people of God.(18*) In the first place we must recall the people to whom the testament and the promises were given and from whom Christ was born according to the flesh.(125) On account of their fathers this people remains most dear to God, for God does not repent of the gifts He makes nor of the calls He issues.(126) But the plan of salvation also includes those who acknowledge the Creator. In the first place amongst these there are the Mohammedans, who, professing to hold the faith of Abraham, along with us adore the one and merciful God, who on the last day will judge mankind. Nor is God far distant from those who in shadows and images seek the unknown God, for it is He who gives to all men life and breath and all things,(127) and as Saviour wills that all men be saved.(128) Those also can attain to salvation who through no fault of their own do not know the Gospel of Christ or His Church, yet sincerely seek God and moved by grace strive by their deeds to do His will as it is known to them through the dictates of conscience.(19*) Nor does Divine Providence deny the helps necessary for salvation to those who, without blame on their part, have not yet arrived at an explicit knowledge of God and with His grace strive to live a good life. Whatever good or truth is found amongst them is looked upon by the Church as a preparation for the Gospel.(20*)"
Now, as for the offending statement, “…there are the Mohammedans, who, professing to hold the faith of Abraham, along with us adore the one and merciful God…” Can we read this as an if…then? Did Jesus and Paul never carefully word a statement so that discernment was required? The question has come up here, What is this doing here in the first place? (Or in the CCC, at least.) What is any of this doing here? Why would the Catholic Church affirm solidarity with humanity, regardless of belief system, when she clearly spells out that “Whosoever, therefore, knowing that the Catholic Church was made necessary by Christ, would refuse to enter or to remain in it, could not be saved.” Is there a larger message here? Did the Pope and bishops and periti at Vatican II not know what they were doing when they went through a list of all the religions and religious tendencies and try to find common ground with them all? How foolish of those 100’s of men not to know that Islam is at odds with Christianity. As St. Paul said, “I speak as a fool.” If you were to speak to a Moslem, would it be wrong to say, “You profess to hold the faith of Abraham. Therefore we both adore the one and merciful God, don’t we?” And go from there. If you don’t go from there, then no, there’s no point.
