But as far as Christ is concerned, I couldn't be more in agreement with you. Only He is our salvation,

Did Christ save you on the cross? What do you mean by "salvation"

[jobim]

Of course. Only through Christ's perfect immolation was mankind redeemed. That is salvation, the free, unearned, unmerited free gift, which we receive only through the grace of Christ Himself.

Where you & I might differ is on whether or not that saving grace can be lost by us, and I believe you must know that Catholics do believe it can. A free gift can most certainly be rejected, bringing no benefit to the intended recipient.
