There broke out a violent struggle between the two political parties in 1871, with the issue of the Catholic Programme. This famous document was a manifesto prepared by a group of editors and lawyers, who, in their own words, 'belonged heart and soul to the ultramontane school'—Trudel, Desjardins, M'Leod, Renault, Beausoleil, and others—and was drawn up by A. B. Routhier, then a lawyer in Kamouraska. It sought to lay down a policy to govern all good Catholics in the coming elections. The doctrine of the separation of church and state, the document declared, was impious and absurd. On the contrary, the authorities of the state, and the electors who chose them, must act in perfect accord with the teachings of the Church, and endeavour to safeguard its interests by making such changes in the laws as the bishops might demand. To secure this end the Conservative party must be supported. When two Conservatives or two Liberals were running, the one who accepted the Programme was to be elected; where a Conservative and a Liberal were opposed, the former would be supported; if it happened that a Conservative who opposed the Programme was running against a Liberal who accepted it, 'the situation would be more delicate'—and Catholics should not vote at all.

This frank declaration of war on the Liberal party, this attempt to throw the solid Catholic vote to the Conservatives, at once aroused violent controversy. Bishops Bourget and Laflèche announced that they approved the manifesto in every point, while Archbishop Taschereau and the bishops of St Hyacinthe and Rimouski declared that it had not their authorization.

The Liberal party was sorely pressed. In the emergency some of its moderate members determined to throw off the incubus of their anti-clerical traditions by reorganizing and renaming the party. So in 1871 Louis Jetté and other leading Quebec Liberals undertook to secure a fresh start by organizing the Parti National, and the result of the following elections gave some ground for hope. 'This evolution of the Liberal party,' declared Bishop Laflèche later in a memorial to the Cardinals of the Sacred Congregation, 'had the success expected from it; it made a number of dupes not only among our good Catholics but even in the ranks of the clergy, who had hitherto been united against the Liberal party.... It is from this development that there dates the division in the ranks of the clergy on the question of politics.'

But this prudent step did not avert the wrath of the now dominant ultramontane section. In 1873 a brief pastoral was issued by all the bishops condemning Catholic Liberalism in vague but sweeping terms. Two years later another joint pastoral, that of September 22, 1875, went into the whole question elaborately. Catholic Liberalism, that subtle serpent, was again denounced. The right of the clergy to intervene in politics was again upheld, whether in neutral matters in which they, like all other citizens, should have a voice, or in matters affecting faith or morals or the interests of the Church. In the latter case the clergy should declare with authority that to vote in this or that way is a sin, exposing the offender to the penalties of the Church. In a letter issued a year later Archbishop Taschereau modified these pretensions, but the assault went on. Regarding the identity of the Catholic Liberals in question both pastorals were silent, but not silent were many of the clergy who interpreted them to their flocks. The cap fitted the Liberal party and its chiefs, they averred, and good Catholics must govern themselves accordingly.

This determined attempt of a section of the clergy to use the influence they possessed as spiritual guides to crush one political party aroused the most moderate sections of the Liberals to counter-attacks. The election law of Canada, copied from that of England, forbade the use of undue influence in elections, and undue influence had been said to include use by ecclesiastics of their powers to excite superstitious fears or pious hopes. Baron Fitzgerald had declared in the Mayo case in Ireland, in 1857, that the priest must not use threats of punishment here or hereafter, must not threaten to withhold the sacraments or denounce voting for any particular candidate as a sin. The Liberals of Quebec had no desire to deny the priest the same rights as other citizens enjoyed, of taking part in the discussion of any political question whatever, and using all the powers of persuasion to secure this end. But, they insisted, for a priest to threaten eternal punishment was as much a case of undue influence as for an employer to threaten to dismiss a workman if he would not vote for a certain candidate, and as just a ground for voiding an election. The matter was pressed to a decision in appeals against candidates returned in two federal by-elections, in Chambly and Charlevoix, and in one provincial election, in Bonaventure. In these instances the proof of open partisanship and open use of ecclesiastical pressure was overwhelming. 'The candidate who spoke last Sunday,' declared one priest in Chambly, 'called himself a moderate Liberal. As Catholics you cannot vote for him; you cannot vote for a Liberal, nor for a moderate Liberal, for moderate is only another term for liar.' 'The Church has condemned Liberalism, and to vote against the direction of the bishops would be sin,' declared another. 'The sky of heaven is bleu, the fire of hell is rouge,' another more pointedly urged. 'I was afraid,' one witness testified, 'that if I voted for Tremblay I should be damned.' In defence it was urged that, in the first place, the civil courts had no authority over ecclesiastics, at least for acts done in their spiritual capacity, and, in the second place, that the Church had a right to defend its interests against attack, and that in using to this end all the powers at its disposal it was employing no undue influence. Judge Routhier, the author of the Catholic Programme, upheld these contentions in the first trial of the Charlevoix case, but the Supreme Court, in judgments delivered by Mr Justice Taschereau, brother of the Archbishop, and by Mr Justice Ritchie, denied the existence of any clerical immunity from civil jurisdiction, and found that the threats which had been made from the pulpit constituted undue influence of the clearest kind. Accordingly they voided the election. Their action met with violent protests from some of the bishops, who, when Judge Casault in the Bonaventure case followed this precedent, sought, but in vain, to have him removed by the Sacred Congregation from his chair in the law faculty of Laval. But in spite of protests the lesson had been learned, and the sturdy fight of the Liberals of Quebec for the most elementary rights of a free people had its effect.
