A change of religion causes, to most of those who make it, a very forcible wrench. It may be, probably it usually is, accompanied by great happiness and a sensation of intense relief; no regrets whatever may be felt that the former faith, with its ministers, ceremonies, and churches have been renounced for ever; on the contrary, the convert may be delighted to be rid of them, and in turning his back upon the religion of his childhood, he may feel that he is dismissing a false teacher who has deceived him, rather than that he is bidding farewell to a guide who has conducted him, however unintentionally, unwittingly, or unwillingly, to the gate of safety. Yet granting, and most emphatically granting, all this, we should not forget that there is another view of his position. Let his rejoicing be ever so great at entering that portal and leaving the land of darkness for the regions of light, be the welcome he receives from his future co-religionists as warm as it may, and be his confidence as great as is conceivable, the convert is none the less forsaking a well-known country for one that is new to him, he is leaving old friends to enter among strangers, and he is exchanging long-formed habits for practices which it will take him some time to understand, to acquire, and to familiarize. A convert, again, is not invariably free from dangers. Let us take the case of Sir Everard Digby. A man with his position, popularity, wealth, intellect, and influence, was a convert of considerable importance from a human point of view, and he must have known it. If he lost money and friends by his conversion, much and many remained to him, and among the comparatively small number of Catholics he might become a more leading man than as a unit in the vast crowd professing his former faith; and although, on the whole, the step which he had taken was calculated to be much against his advancement in life, there are certain attractions in being the principal or one of the principal men of influence in a considerable minority. I am not for a moment questioning Digby's motives in becoming a Catholic; I believe they were quite unexceptionable; all that I am at the moment aiming at is to induce the reader to keep before his mind that the position of an influential English convert, at the beginning of the seventeenth century, like most other positions, had its own special temptations and dangers, and my reasons for this aim will soon become obvious.
