[citation needed] Sylvester was ordained a priest and became a canon of the Cathedral of San Rufino in Assisi.
The story of his change of life is reported that, in 1209, he had initially sold some bricks to Francis, who, after his dramatic renunciation of his family, was on a campaign to repair the rural chapels around the city which had fallen into disrepair.
Falling prey to greed, Sylvester claimed that he had been paid too little for the bricks he had previously sold Francis and demanded a just compensation, which he was given.
[1] Sylvester later came to regret this spirit of greed he found in himself, and he too renounced his position and joined Francis, becoming the first priest in the primitive fraternity.
[1] The cause for his canonization was opened by the Friars Minor and has been accepted by the Holy See for further study.
