Fundamentalists respond to the claim that the pope is the Vicar of Christ by stating, “There is no vicar of Christ on earth except the Holy Spirit!” It is true that he Holy Spirit is a vicar of Christ (John 15:26, 16:12-15), but there may be others also. The term “vicar” means “a substitute; esp. an under-servant [who substitutes].”
“After this the Lord appointed seventy others, and sent them on ahead of him, two by two, into every town and place where he himself was about to come. And he said to them . . . `He who hears you hears me, and he who rejects you rejects me, and he who rejects me rejects him who sent me'” (Luke 10:1-2, 16).
“So we are ambassadors for Christ, God making his appeal through us. We beseech you on behalf of Christ, be reconciled to God” (2 Corinthians 5:20).
“[A]nd though my condition was a trial to you, you did not scorn or despise me, but received me as an angel of God, as Christ Jesus” (Gal. 4:14).
“[Ananias] sold a piece of property, and . . . kept back some of the proceeds, and brought only a part and laid it at the apostles’ feet. But Peter said, `Ananias, why has Satan filled your heart to lie to the Holy Spirit and to keep back part of the proceeds of the land? . . . You have not lied to men but to God.’ When Ananias heard these words, he fell down and died. And great fear came upon all who heard of it” (Acts 5:1-5).
