The case, however, is somewhat different again where the new opinions adopted by a minister amount to an abandonment of the fundamental doctrines of his church. That may not exonerate him from demanding a formal and public declaration of the church, but this being secured, it must affect his relation to the general world. Should it be proved that he may be legally tolerated, he must then consider whether it is his legitimate means of influence, or whether he would be substituting for his own expression the mask of an extinct faith. The ethical principle above affirmed relates to the first practical step of the minister whose beliefs have changed. The progressive and inquiring mind that continues in a church where it is barely tolerated does so at great peril. Where the swift foot agrees to march with the halt the pace must be that of the halt. Sceptical minds occupying pulpits even of liberal denominations are likely to discover, should such engagements end, that they have been unconsciously arresting their own development in finding a conciliatory _modus vivendi_ with the reactionary brethren. There is, indeed, a class of fine intellects, like the great English Broad Churchmen already named, whose comparatively advanced views are the result of larger learning; they have discovered that two and two are four, and gathered courage to deny that the amount is five. These constitute the right leaven by which great organisations are raised to higher standards of knowledge and veracity. But there are original and philosophic inquirers whose particular power were only buried in such organisations, without elevating them. These are due to the corps of pioneers in the direction whither the organisations are advancing. Their task is original research. These cannot wisely wear the uniform of any religious or political party. Mr. Call was such an original mind, and after he had left the English church his course was to the maturity represented in this ripe book on “Final Causes.” But had he not passed eleven of his best years in the church, out of his true habitat, we should have more fruit of this fine flavor. It is therefore a voice from his experience that here reaches us, as from his grave:
