We should, moreover, attempt in some way to put the truth into action, making it to come and go, to speak, question, and reply; and should always keep the scene so fully occupied that the minds of the audience may not be diverted therefrom for an instant. In this respect also, the Rev. Père Lacordaire supplies us with an excellent model. In his discourse on the _Intellectual Society founded by the Church_, he points out the efforts which have been made by the world to destroy the immutability of her doctrine, in a style truly dramatic:--"When every thing else on earth is subject to change, what a weighty prerogative must the possession by others of an unchangeable doctrine be in the estimation of those who do not themselves possess it! A doctrine which some feeble old men, in a place called the Vatican, keep secure under the key of their cabinet, and which, without any other safeguard, has resisted the progress of time, the conceits of sages, the machinations of sovereigns, the downfall of empires, and maintained throughout its unity and identity. A standing miracle this, and a claim which all ages, jealous of a glory which disdained theirs, have attempted to gainsay and silence. One after another they have approached the Vatican, and knocked at the gate with buskin or boot. Whereat Doctrine has come forth under the form of a feeble and decrepit septuagenarian, and has asked:-- "'What do you want of me?' "'Change.' {236} "'I change not.' "'But every thing in the world has changed. Astronomy has changed; philosophy has changed; empire has changed; why are you always the same?' "'Because I come from God, and God is always the same.' "'But know this, that we are masters. We have a million of men under arms, we will draw the sword, and the sword which demolishes thrones may easily be made to behead an old man like yourself, and to tear into fragments the leaves of a book.' "'Attempt it. Blood is the aroma which gives me new youth.' "'Well, then, accept half of my purple; join in a sacrifice to peace, and let us go shares.' "'Keep thy purple, O Caesar; to-morrow we will bury you in it, and will chant over you the _Alleluia_ and _De profundis_, which never change.'" This is something which everybody can understand, and which will always be listened to with pleasure, and with profit to the truth. But further: It is not enough to speak to the mind. That goes a very little way, however powerful our speech may be; for the mind is merely the vestibule of the soul. We must penetrate to the sanctuary of the temple, namely, to the heart. The heart is nearly the whole man, and we are hardly any thing apart from the heart. It is the heart which believes--"with the heart man believeth"--and it is the heart which begets virtues. Moreover, the heart is what God demands from us. {237}
