The ordeal of the novitiate passed through with fidelity, he made his vows as member of the order in 1806, in the small thatched chapel at Grantstown. The marked abilities displayed at this period induced his superiors to select him to be sent with some others to the college of their order at Coimbra, in Portugal, a well-conducted institution, and connected with the celebrated university of that place. As he was afforded all the ample opportunities held out to those attending the university lectures--a privilege accorded only to a few--his mind was immensely enriched, and what is of still greater importance, his ideas were enabled to attain a sturdiness of growth and liberality of expansion which ever afterward distinguished his writings and speeches. In his subsequent examination before a committee of both houses of parliament, he testified to the numerous advantages which were then, as now, derived from a continental education for the priesthood. In his days, indeed, it was no longer, as it had been in 1780, felony in a foreign priest, and high-treason in a native, to teach or practise the doctrines of the Catholic religion in Ireland. Still, the penal laws, although relaxed, had left their evil traces long after their name had ceased to excite terror, even if it occasioned a thrill of hatred in the breasts of those who had so long been subjected to the clanking of their fetters. {46} It seems somewhat of an anomaly for Protestantism, which was inaugurated under the plea of freeing and enlightening the human mind, to sanction the enactment and enforce the execution of laws directly calculated to crush religious freedom, and make it criminal to educate the children of the conquered Catholics. It is, however, but one of the innumerable inconsistencies with which the histories of nations and of creeds regale us at intervals. Whilst young Doyle was deeply engaged in drinking in from the purest and deepest springs theologic lore, and treasuring up in his capacious mind the classic and philosophic eloquence of ancient times, the sound of war disturbed his retirement. A French invasion overturned the independence of the country, and so rapid was the advance of Junot that the vessel which bore away in safety to Brazil the royal family was hastened in its departure by some shots from the conquering army. The peninsular war ensued, in which the Portuguese, aided by the English under Wellington, drove out the irreligious soldiers of the empire. The enthusiasm which inflamed the minds of the natives was taken up by the young students, and among them Doyle shouldered his musket, believing that the best way to prove one's fidelity to truth and justice is to _act_ when action alone is effective.
