To begin with the phenomena grouped around the Formula of Concord we may say, that the movement towards greater religious unity, among the Lutherans was largely stimulated by the brilliant and to Luther’s adherents quite unexpected example of Catholic unity resulting from the religious struggle and particularly from the Council of Trent. Selnecker had insisted that Protestants must endeavour to produce an “evangelical counterblast” to Catholic theology and the Council.[1558] In the case of many others too, it was the harmony and united front of the Catholics at the Council of Trent that served as an incentive to create a similar positive bond between their own Churches. Many once more mooted the question of a Protestant General Council, but others, as for instance Andreæ, pointed out how impossible this would be and what a danger it would involve of even greater dissensions. It was also of advantage to the Protestant writers on theology to have a clearly formulated statement of the Catholic doctrine set before them in the definitions of a General Council and explained in the “Roman Catechism.” Though Luther had distorted beyond recognition the Catholic doctrines he attacked, it was less possible than formerly to doubt—after so solemn a declaration—what the teaching of the despised Church was, or, with a good conscience, to deny how alien to her was the anti-Christian doctrine of which she had been accused. Catholic polemics, too, who were growing both in numbers and in strength, must necessarily have opened the eyes of many to the interior continuity, the firm foundation and the logical sequence of the Catholic propositions and, at least in the case of the learned and unprejudiced, led them to regret keenly the absence of clearness and logic on their own side. The latter holds good in particular of the untenability of the conciliatory Lutheran theology which sought to gloss over all the contradictions and which had given rise to the phantom of the Concordia.
“In the work of unifying Protestant theology,” Janssen justly writes, “no slight service was rendered by the Catholic controversialists and apologists and also and especially by the Tridentine Council and the Roman Catechism. Those who opposed to the hurly-burly and confusion of the new teaching the settled, uniform system of a theology, harmonious and consistent in all its parts, thereby made manifest to the dissentient theologians the defects and the glaring discords which Protestantism presented both in its formal and material principles. The sharply defined terminology and the wealth of speculative matter which they offered stood here also in very good stead.”[1559]
This thought also reminds us of the great store of spiritual treasure that Luther’s Churches carried away with them when they severed their connection with Mother Church. Who can question that Luther bequeathed to his Churches much of the heritage of mysteries which Christianity brought to mankind? Faith in the Holy Trinity; in the Father as Source of all being; in the Eternal Son as the Redeemer and Mediator; in the Holy Spirit as the organ of sanctity; again, in the Incarnation, in Christ and His works, miracles and Resurrection; finally a firm belief in an eternal reward, in the again-rising of every man and the everlasting life of the just; in short all the consoling articles of the Apostles’ Creed must be included amongst the treasures which Luther not only took over from the olden Church but, in his own fashion, even defended with warmth and energy against those who differed from him.[1560]
On Catholic principles we may broadmindedly admit that countless well-meaning men since Luther’s day have found in the doctrine he preached the satisfaction of their religious cravings. Very many erred and still err “in good faith” and “with no stubbornness.”[1561] But wherever there is good faith and an honest conviction of having the best, there a religious life is possible. “This the Catholic Church does not deny when she claims to be the one ark of salvation. One would think that this had been repeated often enough to make any misapprehension impossible on the part of Protestants. As to how far this result is due to the Protestant Churches and how far to the Grace of God which instils into every willing heart peace and blessing, is no open question seeing that the Grace of God alone is the foundation of a truly religious life.”[1562]
But if, on the one hand, Lutheranism owes much to the ancient Church, on the other, we cannot shut our eyes to the fact that the revival in the Catholic Church during the 16th century was indirectly furthered by Luther and his work.
Progress and Gains of Catholicism
There were Catholic contemporaries who pointed out that the going over to Luther of many who were members of the Church merely in name, and whose lives did not correspond with her demands, had a wholesome effect on the Church’s body. This held good of the monasteries in particular. In many places relief was felt and a revival of discipline became possible when those, who had entered the religious life from worldly motives, took their departure in order, as Luther himself lamented, to seek greater comfort in the bosom of the new Church. “God has purged His floor and separated the chaff from the wheat,” wrote the Cistercian Abbot, Wolfgang Mayer.[1563] Augustine Alveld, the Franciscan, portrayed with indignant words the evil lives of many apostate monks and declared with relief that: “Those who were of the same pack and lived among us have now, thanks be to God, all of them run away from their convents and institutions.”[1564] In lesser degree the same was true of the laity.
“Indirectly, though very much against his will, Luther helped to promote the regeneration of the Catholic Church by means of the Council of Trent.”[1565] It was his apostasy which made possible that gathering of the Bishops which hitherto external obstacles, shortsightedness, indolence and worldly aims had prevented.
Theological studies profited by the struggle with Protestantism. More attention was bestowed on the question of man’s natural and supernatural equipment; the dangers with which the excessive spread of Nominalism had threatened the doctrine of Grace were effectually circumvented, and the indispensable need of Grace for any work meritorious for heaven was more strongly emphasised. Thus, on the whole, there was a gain which we must not underrate, a new development of theological lore and a clearer formulation of dogma on threatened points similar to that which had resulted from the great controversies in Patristic times.
