been Jews, now entirely disappears.[648] This conception, in spite of its want of stringency, made an immense impression, and has continued to prevail down to the present time. It has, however, been modified by a combination with the Augustinian doctrine of sin and grace. It was soon reckoned as Paul's conception, to which in fact it has a distant relationship. Tertullian had already adopted it in its essential features, amplified it in some points, and, in accordance with his Montanist ideas, enriched it by adding a fourth stage (ab initio--Moses--Christ--Paraclete). But this addition was not accepted by the Church.[649] 3. _Results to ecclesiastical Christianity._ As we have shown, Irenaeus, Tertullian, and Hippolytus had no strictly systematised theology; they formulated theological propositions because their opponents were theologians. Hence the result of their labours, so far as this was accepted by the Western Church of the third century, does not appear in the adoption of a systematic philosophical dogmatic, but in theological fragments, namely, the rule of faith fixed and interpreted in an antignostic sense[650]. As yet the rule of faith and theology nowhere came into collision in the Western Churches of the third century, because Irenaeus and his younger contemporaries did not themselves notice any such discrepancies, but rather imagined all their teachings to be expositions of the faith itself, and did not trouble their heads about inconsistencies. If we wish to form a notion as to what ideas had become universally prevalent in the Church in the middle of the third century let us compare Cyprian's work "Testimonia", written for a layman, with Novatian's work "De Trinitate".
