Donatist struggle.[243] The view, however--which Cyprian never openly expressed, and which was merely the natural inference from his theory--that the Catholic Church, though the "one dove" ("una columba"), is in truth not coincident with the number of the elect, was clearly recognised and frankly expressed by Origen before him. Origen plainly distinguished between spiritual and fleshly members of the Church; and spoke of such as only belong to her outwardly, but are not Christians. As these are finally overpowered by the gates of hell, Origen does not hesitate to class them as merely seeming members of the Church. Conversely, he contemplates the possibility of a person being expelled from her fellowship and yet remaining a member in the eyes of God.[244] Nevertheless he by no means attained to clearness on the point, in which case, moreover, he would have been the first to do so; nor did he give an impulse to further reflection on the problem. Besides, speculations were of no use here. The Church with her priests, her holy books, and gifts of grace, that is, the moderate secularisation of Christendom corrected by the means of grace, was absolutely needed in order to prevent a complete lapse into immorality.[245] But a minority struggled against this Church, not with speculations, but by demanding adherence to the old practice with regard to lapsed members. Under the leadership of the Roman presbyter, Novatian, this section formed a coalition in the Empire that opposed the Catholic confederation.[246] Their adherence to the old system of Church discipline involved a reaction against the secularising process, which did not seem to be tempered by the spiritual powers of the bishops. Novatian's conception of the Church, of ecclesiastical absolution and the rights of the priests, and in short, his notion of the power of the keys is different from that of his opponents. This is clear from a variety of considerations. For he (with his followers) assigned to the Church the right and duty of expelling gross sinners once for all;[247] he denied her the authority to absolve idolaters, but left these to the forgiveness of God who alone has the power of pardoning sins committed against himself; and he asserted: "non est pax illi ab episcopo necessaria habituro gloriae suae (scil. martyrii) pacem et accepturo maiorem de domini dignatione mercedem,"--"the absolution of the bishop is not needed by him who will receive the peace of his glory (i.e., martyrdom) and will obtain a greater reward from the approbation of the Lord" (Cypr. ep. 57. 4), and on the other hand taught: "peccato alterius inquinari alterum et idololatriam delinquentis ad non delinquentem transire,"--"the one is defiled by the sin of the other and the idolatry of the transgressor passes over to him who does not transgress." His proposition that none but God can forgive sins does not depotentiate the idea of the Church; but secures both her proper religious significance
