Spondent quas non exhibent
Papal decretal promulgated in 1317 by John XXII / From Wikipedia, the free encyclopedia
Spondent quas non exhibent (sometimes referred to as Spondent pariter) is a papal decretal promulgated in 1317 by Pope John XXII forbidding the practice of alchemy.[1][2] The rationale provided for the ban in the decretal is not a specifically theological one,[3] but instead a moral condemnation, with the Pope expounding how fraudulent alchemists exploited the poor and charging them with knowingly engaging in falsehood.[4]
