He came from:
Assisi, from one of the noblest families there, a relation of Clare’s

Character and characteristics:
A man of God of angelic purity, he talked little and was a contemplative

Of him St Francis said:
In his description of the ideal friar he said he should possess “the virtuous and incessant prayer of Rufino, who prayed even when he slept and in anything he did he incessantly held his spirit in union with the Lord…” (Speculum Perfectionis 85/1782 .
And “St Francis used to say of him that Brother Rufino had been canonized in Heaven by the Lord Jesus Christ while he was still alive and that he would not hesitate to say “St Rufino” (except in his presence) though he was still living on earth” (The Little Flowers, Chap XXIX p.115).

His life:
He did not like to preach and once, when he had refused to do so, Francis said: “Because you did not obey me at once, I also command you under holy obedience to go to Assisi naked – wearing only your breeches – and to go into some church and preach to the people naked like that”. Rufino obeyed and at that point St Francis, thinking of the prompt obedience of Rufino, one of the gentlest men in Assisi and of his harsh command, started to reproach himself saying: “How can you, the son of Peter Bernardone, you vile little wretch, order Brother Rufino, who is one of the noblest citizens of Assisi, to go naked and preach to the people like a madman? By God I am going to see to it that you yourself experience what you order others to do”. And having said that, in the fervour of the Holy Spirit, he too immediately took off his habit and went to Assisi naked, accompanied by brother Leo, who very discreetly carried along the Saint’s habit and Brother Rufino’s (The Little Flowers, Chap XXX p. 116).
Rufino is also the protagonist of a very touching episode: his encounter with the devil in the form of a crucifix that reduced him to a state of confusion and doubt, both towards Francis and about his own path so that he no longer wished to see Francis. Masseo stood by him, but it was Francis who put an end to Rufino’s crisis, after the spirit had revealed the condition in which the friar found himself. “Oh Brother Rufino, you naughty boy, whom have you believed?” When he came the saint told him in detail all about the temptation, exterior and interior, which he had suffered from the devil, not from Christ, and therefore he should in no way consent to his suggestions. “But when the devil says to you again: ‘You are damned’, you answer him confidently: ‘Open your mouth and I will shit in it’, and let it be a sign to you that he is the devil that when you say those words, he will immediately go away… Brother Rufino, seeing that St Francis had told him in detail all about his temptation, and being moved to remorse by his words, began to weep bitterly and knelt before him and humbly acknowledged his fault in having concealed his temptation from him. And he remained greatly consoled and comforted by the advice of the holy Father and completely changed for the better.
Finally St Francis said to him: ‘Go to confession, son. And do not stop devoting yourself to your usual prayers. And know for sure that this temptation will be helpful and consoling to you, as you will find out in a short while’… (The Little Flowers, Chap XXIX p. 113-4). The Devil returned but could accomplish nothing and fled away causing a great fall of rocks from mount Subiaso and a real vision of Christ consoled poor Rufino (The Little Flowers, Chap XXIX p. 114-5).
He touched Francis’ wound in his side, hurting him, while he was massaging him; for Francis never showed anyone his stigmata. “‘For this reason our Lord suffered greatly’ and removing his hand, he prayed groaning that God should forgive him” (T. Celano, Trattato dei miracoli Chap II/829). With Leone and Angelo, Rufino is supposed to have written the Legenda Trium Sociorum, which begins: “To the reverend father in Christ, Brother Crescenzio, by the grace of God our General Minister, Brother Leo, Brother Rufino and Brother Angelo, who in the past were the companions, without merit, of our blessed Father Francis, express their dutiful and devoted reverence for our Lord…”

He died:
at the Portiuncola, probably in 1270

He is buried:
in the crypt of St Francis with three companions: Masseo, Leo and Angelo, as well as Brother James dei Settesoli.
