The scope of the Church’s answer covers the whole field of theological thought. But because there are no existing sources of Marcion’s theology, except those contained in the answers of Christian writers, and, because even these writers have been selective, the scope of this study was necessarily limited to the basic problems of God, Scriptures, Christology, and Eschatology. The thesis of this study was that the Church, through Tertullian and Irenaeus, had answered Marcion’s attack thoroughly and decisively for the edification of the Church of Christ. For the purpose or proving this thesis, this study presents a brief outline of Marcion\u27s development and place in the Church; secondly, a brief sketch of the men who opposed him; finally, an antithetical presentation of the teachings of Marcion and the Church on Scripture, God, Christology, and Eschatology, in that order. This presentation was achieved by reconstructing Marcion’s theology from the writings of Irenaeus and Tertullian, and from a number of more recent evaluations of Marcion
