"The eventual development of a clear concept of the supernatural in Christian theology was promoted both by dialogues with heretics and by the influence of Neoplatonic philosophy." Benson Saler: Supernatural as a Western Category. Ethos 5 (1977): 44
"Saint Thomas's important contribution to the emergence of a technical theology of the supernatural represents a special development of the concept of surpassing effects. Saint Thomas and others of the Scholastics have left us as one of their legacies a dichotomy between the natural and the supernatural that is theologically rooted in the distinction between the Order of Nature and the Order of Grace." Benson Saler: Supernatural as a Western Category. Ethos 5 (1977): 47-48
