One miracle of note, as Eusebius testified, had occurred during the Easter Vigil when Narcissus changed water into oil to supply all the lamps of the church.

[3][4] Narcissus was the subject of several serious allegations made by members of the Christian community, but these proved to be false.

Upon his return to Jerusalem, the people unanimously sought him out and asked him to resume his episcopal duties.

This he did, but owing to his extreme age and the weight of his duties, he made Saint Alexander his coadjutor bishop.

[3] St. Narcissus continued to serve his flock and other churches outside his jurisdiction by his constant prayer and his exhortations to the faithful for unity and peace.
