Derived from the Latin name (Silvanus) means - "one who lives in the woods, of the woods"
Saint Silas or Saint Silvanus (1st century AD) was a leading member of the early Christian community, who later accompanied Paul in some of his missionary journeys. The name from the list of seventy disciples of Christ in the Eastern Christian tradition. Except the twelve apostles [Andrew brother of the Apostle Peter (the fisherman from Bethsaida, a disciple of John the Baptist), Peter (he is Simon son of John, also called Cephas), John the Evangelist, James son of Zebedee, Philip of Bethsaida, Bartholomew Apostle aka Nathaniel, Matthew the tax collector (also Levi Alpheus), Thomas, James the son, Thaddeus son of Alpheus (also known as Jacob or Judah Levi), Simon the Zealot (also Simon the Zealot) and Judas Iscariot (who betrayed Jesus)] Jesus Christ also chosen seventy others: Agabus, Aquila, Amplus, Ananias, Andronicus, Apelles, Apollos, Aristarchus, Aristobulus, Artemas, Archippus, Asyncritus, Achaicus, Barnabas, Gaius, Euodias, Epaphras, Epaphroditus, Epenetus, Erastus, Hermas, Hermes, Zenas, James, Jason, Justus, Herodion, Carpus, Cleopas, Clement, Quadratus, Crescens, Crispus, Quartus, Linus, Lucius, Luke, Mark, John, Narcissus, Nicanor, Olympas, Onesimus, Onesiphorus, Parmenas, Patrobus, Prochorus, Pudens, Rufus, Silvan, Simeon, Sosipater, Sosthenes, Stachys, Stephen, Tertius, Timon, Timothy, Titus, Tychicus, Trophimus, Urban, Thaddeus, Philemon, Philip, Philologus, Fortunatus, Dionysus, Phlegon, Simeon Niger.
There is some disagreement over the proper form of his name: he is consistently called "Silas" in Acts, but the Latin Silvanus, which denotation - "of the forest", is always used by Paul and in the First Epistle of Peter; it may be that "Silvanus" is the Romanized version of the original "Silas", or that "Silas" is the Greek nickname for "Silvanus". Fitzmyer points out that Silas is the Greek version of the Aramaic - "Seila", a version of the Hebrew "Saul", which is attested in Palmyrene inscriptions. The name Latin "Silvanus" may be derived from pre-Roman Italian languages (see, e. g., the character "Asilas", an Etruscan leader and warrior-prophet who plays a prominent role in assisting Aeneas in Virgil's epic poem the Aeneid).
St. Silas is currently commemorated in the Calendar of Saints of the Evangelical Lutheran Church in America on January 26 with Timothy and the Apostle Titus, and separately on July 13 by the Roman Catholic Church and February 10 by the Lutheran Church - Missouri Synod.
