Here then let us put two very pertinent questions, for our non-Catholic friends to ponder over, and to answer, if they can. First: How is it possible for the Church to go astray, if God the Holy Ghost is really guiding? Second: How is it possible for the Church to wander away into error, if this same Spirit be leading her into all truth? Will some one kindly explain that, without at the same time denying the veracity of God?
4. However, granting the absolute truth of Christ’s promises, we may now proceed to inquire in what way this divine and (because divine) infallible guidance into all truth is brought about? Is it by the Holy Spirit whispering to each individual priest or to each individual Bishop? Emphatically not. Why not? Because, if that theory were well founded, then every priest and Bishop would believe and teach precisely the same set of doctrines, without any need of an infallible Pope to guide him. For, clearly, the Spirit of Truth could not whisper “yea” to one, and “nay” to another, nor could He declare a thing to be “black” to one person and “white” to his neighbour. In fine, we have but two alternatives to choose from. We must confess either that the promises themselves, so solemnly made, are lies (which were blasphemy to affirm), or else, that God directs His Church, and safeguards its truth, through its head, or chief Pastor; just as we regulate and control the members of the physical body through the brain. We must either renounce all belief in Christ and His promises, or else admit that His words are actually carried out, and that the prayer has been heard which He made for Peter, and for those who should, in turn, exercise Peter’s office and functions, and should speak in his name. Harken to the narrative, as given by St. Luke: “The Lord said: Simon, Simon, behold, Satan hath desired to have you [observe, the plural number] that he may sift you as wheat; but I have prayed [not for all, but] for thee, that thy faith fail not: and thou, being once converted, confirm thy brethren” (Luke xxii. 32) [observe the singular number, “thee,” “thy” and “thou"].
