Saint Donatus lived during the reign of the holy Emperor Theodosius the Great (379-397) and was bishop of the city of Euroea (in Albania). Not far from this city, in the vicinity of Soreia, was a brackish spring of water. When the saint learned of this, he went with clergy to the spring and cast out a monstrous serpent, which died. The saint prayed, he blessed the spring and drank the water without harm. Seeing this miracle, the people glorified God.
Another time, St Donatus prayed and brought forth water from a dry and rocky place, and during a drought he entreated the Lord to send rain to the parched land.
The daughter of the holy Emperor Theodosius fell terribly ill and was afflicted by an unclean spirit. St Donatus came to the palace, and as soon as he arrived the devil left and the sick woman was healed.
A certain man, shortly before his death, repaid a loan to a money-lender. The creditor tried to extort the money a second time from the dead man’s widow. The saint resurrected the dead man, who told where and when the loan had been repaid. After obtaining a receipt from the creditor, the man fell asleep in the Lord.
St Donatus reposed in peace about the year 387.
