Newman darüber, was Glaube ist

»[F]aith has two peculiarities;—it is most certain, decided, positive, immovable in its assent, and it gives this assent not because it sees with eye, or sees with the reason, but because it receives the tidings from one who comes from God. This is what faith was in the time of the Apostles, as no one can deny; and what it was then, it must be now, else it ceases to be the same thing. I say, it certainly was this in the Apostles' time, for you know they preached to the world that Christ was the Son of God, that He was born of a Virgin, that He had ascended on high, that He would come again to judge all, the living and the dead. Could the world see all this? could it prove it? how then were men to receive it? why did so many embrace it? on the word of the Apostles, who were, as their powers showed, messengers from God. Men were told to submit their reason to a living authority. Moreover, whatever an Apostle said, his converts were bound to believe; when they entered the Church, they entered it in order to learn. The Church was their teacher; they did not come to argue, to examine, to pick and choose, but to accept whatever was put before them. No one doubts, no one can doubt this, of those primitive times. A Christian was bound to take without doubting all that the Apostles declared to be revealed; if the Apostles spoke, he had to yield an internal assent of his mind; it would not be enough to keep silence, it would not be enough not to oppose: it was not allowable to credit in a measure; it was not allowable to doubt. No; if a convert had his own private thoughts of what was said, and only kept them to himself, if he made some secret opposition to the teaching, if he waited for further proof before he believed it, this would be a proof that he did not think the Apostles were sent from God to reveal His will; it would be a proof that he did not in any true sense believe at all. Immediate, implicit submission of the mind was, in the lifetime of the Apostles, the only, the necessary token of faith; then there was no room whatever for what is now called private judgment. No one could say: "I will choose my religion for myself, I will believe this, I will not believe that; I will pledge myself to nothing; I will believe just as long as I please, and no longer; what I believe today I will reject tomorrow, if I choose. I will believe what the Apostles have as yet said, but I will not believe what they shall say in time to come." No; either the Apostles were from God, or they were not; if they were, everything that they preached was to be believed by their hearers; if they were not, there was nothing for their hearers to believe. To believe a little, to believe more or less, was impossible; it contradicted the very notion of believing: if one part was to be believed, every part was to be believed; it was an absurdity to believe one thing and not another; for the word of the Apostles, which made the one true, made the other true too; they were nothing in themselves, they were all things, they were an infallible authority, as coming from God. The world had either to become Christian, or to let it alone; there was no room for private tastes and fancies, no room for private judgment.«
