"godly and wholesome doctrine" is no longer obliged to be read and
taught by Anglicans; probably they no longer consider it either
"godly" or "wholesome," but quite the reverse. This we are quite ready
to admit. But, in the name of common prudence, who, in his senses,
would trust the salvation of his immortal soul to a Church that
teaches a thing is white in one century and black in the next, and
never knows its own mind?

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
