Leo II
pope
Feast: 3 July (not on the universal Roman calendar; kept in the Roman Martyrology or local calendars)
Who they were
Leo, a Sicilian, was elected pope in 681 and consecrated on 17 August 682. The chief act of his short pontificate was to confirm the Sixth Ecumenical Council, which condemned the Monothelite heresy.
Described by his biographer as just and learned, he died on 28 June 683 and is commemorated as a saint in the Roman Martyrology.
The miracles
There was never a formal cause: he has been honoured as a saint since before the Church's formal processes began.
Why that counted as sanctity
A just and learned pope who confirmed the faith about Christ's two wills.
