The next subject proposed for examination was Original Sin. The Emperor showed the greatest anxiety to secure a delay, and at a hint from him several of the Spanish bishops tried to postpone a decision by prolonging the discussions and by raising the question of the Immaculate Conception of the Blessed Virgin. That the Fathers of Trent were not opposed to this doctrine is clear enough from the decrees they formulated, but the majority of them were of opinion that purely domestic controversies among Catholic theologians should be left untouched. In the fifth general session (17th June 1546) it was defined that by his transgression of the commandment of God the head of the human race had forfeited the sanctity and justice in which he had been created, and had suffered thereby in both soul and body, that in doing so he had injured not merely himself but all his descendants, to whom Original Sin is transmitted not by imitation merely but by propagation, that the effects of this sin are removed by the sacrament of Baptism, necessary alike for adults and infants, and that the concupiscence, which still remains in a man even after baptism has produced its effects, is not in itself sinful. It was declared, furthermore, that in the decrees regarding the universality of Original Sin it was not intended to include the Blessed Virgin or to weaken the binding force of the decrees issued by Sixtus IV. regarding her Immaculate Conception.
The way was now cleared for the question of Justification.[1] This was the doctrine on which Luther first found himself in disagreement with the Church, and which he put forward in his sermons as the foundation of his new gospel. The importance of the subject both in itself and in the circumstances of the time cannot be exaggerated, nor can it be contended that the Fathers at Trent failed to realise their responsibilities or to give it the attention it deserved. Had they done nothing else except to give to the world such a complete and luminous exposition of the Catholic teaching on Justification their meeting would not have been held in vain. In the 6th public session (13th January 1547), at which there were present besides the legates, ten archbishops, forty-two bishops, two procurators, five generals of religious orders, two abbots and forty-three theologians, it was defined that, though by the sin of Adam man had lost original justice and had suffered much, he still retained free-will, that God had been pleased to promise redemption through the merits of Jesus Christ, and that baptism or the desire for baptism is necessary for salvation. The decrees dealt also with the method of preparing for Justification, with its nature, causes, and conditions, with the kind of faith required in opposition to the confidence spoken of by the Reformers, with the necessity and possibility of observing the commandments, with the certainty of Justification, perseverance, loss of Grace by mortal sin, and with merit. The 7th public session (3rd March) was given to decrees regarding the Sacraments in general and Baptism and Confirmation in particular.
Meanwhile the long-expected civil war had begun in Germany, and Europe awaited with anxiety the result of a struggle upon which such momentous interests might depend. Charles, supported by most of the Catholic and not a few of the Protestant princes, overthrew the forces of the Elector of Saxony and of Philip of Hesse (1547) and by his victory found himself for the first time master in his own territories. Coupled with rejoicing at the success of the imperial arms there was also the fear in many minds that the Emperor might use his power to overawe the Council, and force it to agree to compromises, which, however useful for the promotion of unity in Germany, might be subversive of the doctrine and discipline of the Church and dangerous to the prerogatives of the Holy See. The selection of Trent as the place of assembly for the council was never very satisfactory to the Pope, but now in the changed circumstances of the Empire it was looked upon as positively dangerous. An epidemic that made its appearance in the city afforded an excellent pretext for securing a change of venue, and at the 8th public session (11th March 1547) a majority of the members present voted in favour of retiring to Bologna. The legates accompanied by most of the bishops departed immediately, while the bishops who supported the Emperor remained at Trent. For a time the situation was critical in the extreme, but under the influence of the Holy Ghost moderate counsels prevailed with both parties, and after a couple of practically abortive sessions at Bologna the council was prorogued in September 1549. A few months later, November 1549, Paul III. passed to his reward.
