Saint Silvanus was one of the Seventy Apostles chosen and sent forth to preach by Christ (Luke 10:1).
Silvanus preached the Word of God together with the chief Apostles Peter and Paul. The holy Apostle Peter mentions him in his first Epistle: “By Silvanus, a faithful brother to you, as I suppose, I have written briefly...” (1 Pet 5:12). Saint Silvanus was made bishop at Thessalonica and died there as a martyr, having undergone many sorrows and misfortunes for the Lord’s sake.
Saint Silvanus is also commemorated on July 30 together with with Saints Silas, Crescens, Epenetus and Andronicus.
