This work by the Irish monk Sedulius Scottus elaborates on the differences between argument and argumentation, particularly in the context of the Gospels, focusing on the Gospel of Matthew. It highlights Matthew's Jewish heritage and the significance of his lineage, detailing the seven gifts bestowed upon him and the importance of his writing. The text also outlines the structure of Matthew's Gospel, including the circumstances of its writing, its content, and its theological implications, especially regarding the genealogy of Christ, which connects Him to Abraham and David.
