Systematized theology

"Jesus, as has been intimated, did not teach a Dogmatic Theology; but only imparted, in a fragmentary form, the eternal truths of the religion of Heaven. The Apostles, particularly Paul and John, formed indeed a system of doctrines; but not a sharply-defined and logical system like that of the Schoolmen of the middle ages, and those Schools of Theology of our day. It was long, however, before believers at large began to build up the doctrines of Christianity in a connected and systematic manner. At first they were satisfied with the simple confession that Jesus of Nazareth is the Christ, that he is the Messiah promised by the prophets, and that he is the Son of God and the Saviour of the world." -- History of the Early Baptists: from the 'Beginning of the Gospel' to the rise of affusion as baptism, and of infant baptism 28 A.D.--250 A.D., William Cecil Duncan, New Orleans, LA: Alex Duncan & Co., 1857pp. 162, 163
