A:
The Catholic Church teaches that St. Linus was the second bishop of Rome and was appointed by Peter himself. In practice, we know nothing certain about Pope Linus and can not even be sure whether a person of that name ever lived.
Francis A. Sullivan SJ (From Apostles to Bishops) says that most scholars are of the opinion that, in spite of Church tradition, the early church of Rome was led by a group of presbyters, and that bishops were not appointed to the church in Rome until later in the second century. In other words, there can have been no Pope Linus, although it is conceivable there was a presbyter of than name.
Pope St. Anacletus (Cletus) (76-88) followed Linus.
The first two successors of St. Peter as the head of the Universal Church were St. Linus, who served as pope from around 67 to 76 AD, and St. Anacletus (or St. Cletus), who served as pope from around 76 to 88 AD.
St. Linus became pope at the death of St. Peter.
There were a lot of saints immediately after St. Peter, but the pope who followed him, who was also acclaimed a saint was Pope St. Linus (67-76).
There was no delay. Pope Linus took office soon after the death of St. Peter.
Pope St. Linus was the second pope of the Catholic Church who succeeded St. Peter. He was a martyr and his feast day is celebrated on September 23. He is known for establishing the hierarchical structure of clerical orders within the Church.
Pope Saint Linus' papacy lasted nine years from 67 AD to 76 AD.
There has never been a Welsh pope but there has been one pope from England - Nicholas Breakspear who took the name of Pope Adrian IV. The mother of Linus the first pope after St. Peter was Welsh, that makes him half Welsh.
After St. Peter, St. Linus became pope of the Church. Whether Peter specially choose Linus is debatable since his successor was chosen in his absence: Peter was dead when Linus became pope. Popes are now elected by a conclave. At the beginning of the Church it might have been different, as Matthias had been elected by the apostles by drawing straws, but as to Linus' election, little is known about procedure. Whatever the case, Peter was a Jew only by ancestry, not by Faith, for he had become a Christian. Linus was not a pagan, but a Christian as well. Therefore, even if Peter had specifically requested Linus as the next pope, he was only choosing another Christian he felt capable of the office.
Linus is not a patron saint.
Catholic AnswerThe successor to Saint Peter, and the Bishop of Rome, is the Vicar of Christ and the Holy Father, the Pope, who resides in the Vatican. As of April 2012, it has been Pope Benedict XVI since he was elected in 2005 after the death of Pope John Paul II.
