When did St. Sylvester become pope?

Answer 1

Tradition says that Linus became pope around 64 to 67 CE, but this should be treated with caution. Even the Catholic Encyclopedia concedes we know little about the early popes and nothing reliable about their chronology.

In fact, there probably was no first century bishop or pope named Linus. Francis Aloysius Sullivan (From Apostles to Bishops: The Development of the Episcopacy in the Early Church) says that the consensus of scholars is that the available evidence indicates that the church of Rome was led by a college of presbyters, rather than a single bishop, for at least several decades of the second century. This consensus is backed up by an analysis of early Christian writings.
