Scholarly Reflections
Massaux, Éduard. "Chapter One: Aristides of Athens." The Influence of the Gospel of Saint Matthew on Christian Literature before Saint Irenaeus: Book 3: The Apologists and the Didache. (Translated by Norman J. Belval and Suzanne Hecht. Macon, Georgia: Mercer University Press, 1993, 5-9.
Aristides of Athens wrote an apologetic work to Hadrian, which was found in a Syriac version in 1889 (Massaux 1993, 5). The work would seem to have been quoted, even possibly in full, in other sources. Massaux observes that Aristides suggests Hadrian can verify what he says relatively easily, by consulting existing Christian writings, which would apparently be readily available to him (Massaux 1993, 6). Though many themes in the work are in common with themes in Matthew, Massaux finds no actual direct evidence of dependence.
While Massaux finds no clear evidence of Aristides' use of any of the Gospels (not just Matthew), he does find an apparent familiarity with Paul. This is evident through an apparent allusion to Romans 1:23, another to Romans 1:22, and a reference to 1 Timothy 6:16 (Massaux 1993, 7). There is a further similarity of thought to 1 Thessalonians 3:13, though with different wording (Massaux 1993, 8).
