Ames: original righteousness a moral condition owed to a nature made to act justly
William Ames, in volume 4, chapter 1 of his Bellarmine Disarmed, explains how original righteousness was natural to the first man: "We do not say that this righteousness was an essential part of physical nature or flowed from its principles in a physical way. We say it was a moral condition owed to that nature, which was created to act righteously."
Latin
XXVIII. Amesius in Bellarmino Enervato tomo quarto capite primo, explicans quomodo justitia Originalis primo homini naturalis fuerit, Nos non dicimus, inquit, justitiam illam fuisse vel essentialem partem naturae Physicae, aut Physico modo ex ejus principiis fluere, sed conditionem esse moralem naturae illi debitam, quae ad juste operandum fuit creata.
