Yes, but it is the catholic who supplants the exclusive claim of salvation in only Christ as I noted in the Greek with the false promises of the apparitions claiming that the one that recommends themselves to it shall not perish.
You are perhaps breaking this off, somehow, from the fact that we are a part of the salvation of everyone else in the Mystical Body of Christ, having a share in His ctivity and His work as His limbs, organs and senses, sharing and circulating all our spiritual gifts, through Christ our Head and through His grace only. We participate in one anothers' salvation precisely because we are one in Christ.
One in Christ. Everything with Him. Everything in Him. Everything through Him. Nothing apart from Him.
We are even partakers in His divine nature. Did you know that?
