Infiniti contemplatio provides the first thorough inquiry of Zwingli’s roots in late medieval, particularly Franciscan, thought - based on an extensive editorial appendix presenting annotations of Zwingli to Duns Scotus, Stephanus Brulefer, the Theologia Damasceni and extracts of Konrad Summenhart and John Eck.
After a survey of previous research (part I), the evolution of the Scotistic ideas of actual infinity and formal distinction is traced from high scholasticism via Duns, Mayronis, Ockham, Brulefer, Mair and others up to about 1510 (part II), leading to Zwingli’s reception, manifest from 1525 onward and contributing to Reformed confessionalization (part III).
A key for Zwingli’s adaption of scholasticism proves to be a distinctly dual, but partially convergent reception of Scotus in Scotism and Ockhamism - and hence the two wings of early Reformation.
