Who they were

Celestine, a Roman, became pope in 422 without opposition. A close friend of St Augustine, after his death he defended his memory against the Semipelagians.

He sent Palladius as bishop to the Irish in 431, and afterwards St Patrick received his commission. He is honoured in the Greek Church too for condemning Nestorius. He died on 26 July 432.

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
