It would be unchristian to even be concerned about other ways to God. We know how to come to Christ; we do so in every Liturgy. If there are other ways to Him, great; but when ours is presented to us every week, what need have we of knowing whether there is another, more difficult path?
This is the most correct answer. And the answer to JoeS' Question:
Then how would you explain 'No one comes to the Father except through Me' statement that our Lord said? Was this just a momentary idea of His or was he serious. Did Christ really mean this? How would this statement impact the Jews and Muslims? I am well aware of the "mercies of God" answers for this, but I am trying to get an answer to is: why should any of us care what religion we belong to as long as it's God centered?
Jesus is the way, and we should only concern ourselves with this. Because in all honesty, we don't know the answer and we should leave that judgement with the Lord himself.
A wise man once says, "Be avid for that which benefits." And the only that benefits a believer are those matters which pretain him and the means by which he follows the Lord's commendments.
On the last day when A believer stands before the Lord, he isn't
going to be asked, "Do Muslims worship the same God is you?"
A believer however might be asked, "Did you worship the one true God?"
Judgement is for the Lord not us, our business is to adhere to His commendments.
So I guess the best answer is to refrain our judgement and be concerned with ourselves and what we are doing to please our Lord.
And the Lord knows best.
