"By a Catholic, then," I continued, "I mean a Christian who is a member of that vast, world-wide society which is generally known and called, by friend and foe, the Catholic Church, the spiritual head of which is the Bishop of Rome. This church, or united body—for you know the word church is the same as ecclesia in Latin or Greek, and means 'an assembly,' or 'united body'—this united body we call catholic, or universal, because it has always vastly outnumbered all other divided bodies of Christians, whether taken singly or all put together. The number of Catholics in the world is usually stated to be two hundred millions; of Russian, Greek, and Oriental schismatics about ninety millions, and Protestants of all denominations about seventy millions. This vast united body, as it has always borne the name of Catholic, so is it the only body of Christians that can be called the catholic or universal church, if we attach any meaning to the word as a definition of the visible church, such as we find set down in the Creed, 'I believe in the Catholic Church.' However, as the name Catholic is sometimes claimed in some indefinable sense by other bodies of Christians, those to whom it belongs of right, and by the force of terms, have no objection, for the sake of distinction, to the term sometimes applied to them, of Roman Catholic, meaning merely the real catholics; that is to say, those who, though universal, or spread everywhere, are yet united in one visible society, through being all in communion with the Bishop of Rome; being Roman in their centre of unity, and Catholic in their world-wide circumference.
"Thus the Catholic Church, alone of all Christian bodies, bears, as it it were, written on her forehead, that mark of unity divinely impressed by her Heavenly Founder and preserved by the power of his dying prayer, as a perpetual note of her heavenly origin. 'I pray thee, O Father, that they may be one in us, that the world may believe that thou hast sent me.'
"I think that you will admit that the old church founded by our Lord was to have on her these marks of unity and universality, and that these marks are to be found on no church at the present day but the church Catholic."
"Yes," he replied after a moment's reflection, "I think this may fairly be admitted; but unity is not all that our Lord prayed for; in the same prayer he said, 'Holy Father, keep them in thy truth,' and we say that the old church fell away, and that it no longer teaches the essential truths of the gospel, or has obscured them by false doctrines."
"Well, let that pass for the moment," I replied. "We will see later on whether you will continue to maintain these propositions. I will now state the principal points on which we are agreed with Protestants, and afterward the distinctive points on which we differ from them. And I think you will admit that the points on which we are agreed with you are precisely every one of those points which you would consider to be the great essential, fundamental doctrines of the gospel. We believe, then, in the unity and trinity of God, three coequal persons, one in substance, and in the incarnation of God the Son, who became the Son of Blessed Mary, ever Virgin, of the substance of his mother according to his manhood, as he had been from all eternity God the Son, of one substance with the Father—God of God. So we believe and hope for redemption and grace, to do good works acceptable to God, and which he will reward amply and solely from and through Christ our Lord, and in prayer, love, repentance, obedience, and holiness, as conditions of our salvation through him. And we believe that eternal perdition and endless woe will be the lot of those 'who neglect so great a salvation.' We believe also that all Holy Scripture is written by divine inspiration, and when studied and rightly understood, by aid of God's Holy Spirit, is most profitable for instruction in all Christian perfection. In a word, Catholics believe all that religious Protestants consider to be of the essence of true religion; and they also reject every tenet or position which can clash with these paramount truths of revelation. A Protestant, therefore, in becoming a Catholic, has to give up nothing which he believes essential in religion. No doubt he would have to add to his faith certain other truths which at present he does not hold, because he has not come to see that they are parts of revealed truth."
"I have not lost a word," he replied, "of what you have been saying. I confess it is quite a new light to me, that all these doctrines which you have stated are part and parcel of the Catholic faith; but, my dear Philip, I cannot help fancying that all Catholics are not like you, for I have always heard that they denied or obscured nearly every one of these doctrines."
"As for these statements of doctrine not being the authorized teaching of the church, I can only say that you will find them all stated fully by the authorities of our church in the canons and catechism of the Council of Trent, and stated briefly in every child's catechism. Yet, notwithstanding, as you say, Protestants generally seem to think that they know our religion better than we do ourselves; although they seldom read our books, they insist on denying that we really do hold these points which we profess to hold in common with them; but I think you will admit that we ought to be allowed to know our own creed best. It is a wonder that they do not rather rejoice to believe that we have so many points of faith in common, and those the very points in which they consider the essence of true religion to consist. It seems as if they had an instinctive feeling that the strength of their position would be broken up if once if should appear that the differences between themselves and the old religion were on but few points, and those such as they do not consider the most essential."
"Well, anyhow," he rejoined, "whatever be the reason, there is a strong prejudice on both sides; Protestants are as strongly convinced that you are in the wrong as you Catholics are convinced that you are right. One or other of us must be wrong; and if we assert that you are wrong against such a strong conviction on your part, and one that has subsisted for so many ages, and been held by such a vast majority, why, we are forced to admit that our strong conviction against you is no argument that we are in the right. But you can't deny that such a strong conviction as ours must have some foundation in reason."
