Pope Shenouda III
Belief in Christ is a matter of salvation. The salvation of man depends upon belief in Him. That is why St. Paul and St. Silas said to the jailer at Philippi: "Believe on the Lord Jesus Christ, and you will be saved, You and your household' (Acts 16:31). Naturally this would be accomplished provided that he walked in the things connected with this belief, for example: "He who believes and is baptized will be saved" (Mk. 16:16).
