The first known written use of "Catholic Church" appears in a letter by St.Ignatius of Antioch about A.D. 107 to the church of Smyrna, whose bishop, Polycarp, visited Ignatius during his journey to Rome as a prisoner: in his letter to Smyrna, Ignatius wrote, "Let no man do anything connected with the Church without the bishop. Let that be deemed a proper Eucharist, which is [administered] either by the bishop, or by one to whom he has entrusted it. Wherever the bishop shall appear, there let the multitude [of the people] also be; even as, wherever Jesus Christ is, there is the Catholic Church." (Letter to the Smyrnaeans, 8) His use of "Catholic Church" suggests that it was already in current use, for he sees no need to explain himself and uses the expression as one already known to his readers. It gives expression to St. Paul's teaching that all baptized in Christ are one body in Christ (Gal.3:28; Eph.4:3-6, 12-16). Dissenting groups breaking away from this universal unity were already known to the Apostles: in his letters Paul refers to the "Judaizers" (those requiring observance of the Jewish Law), and in his Book of Revelation St. John calls them "Nicolaitans". It is a small step for those faithful to the teaching of the Apostles to identify themselves as the Catholic Church ("the one Church everywhere"), and not to include those dissenting and breaking away from unity with her.
The term Catholic Christianity entered into Roman law by force of edict under the Roman Emperor Theodosius on February 27 AD 380 in the Theodosian Code XVI.i.2: "It is our desire that all the various nations which are subject to our clemency and moderation, should continue the profession of that religion which was delivered to the Romans by the divine Apostle Peter, as it has been preserved by faithful tradition and which is now professed by the Pontiff Damasus and by Peter, Bishop of Alexandria, a man of apostolic holiness. According to the apostolic teaching and the doctrine of the Gospel, let us believe in the one Deity of the Father, the Son, and the Holy Spirit, in equal majesty and in a holy Trinity. We authorize the followers of this law to assume the title Catholic Christians; but as for the others, since in our judgment they are foolish madmen, we decree that they shall be branded with the ignominious name of heretics, and shall not presume to give their conventicles the name of churches. They will suffer in the first place the chastisement of divine condemnation and the second the punishment of [as] our authority, in accordance with the will of heaven, shall decide to inflict."

Thurstan, or Turstin (c. 1070–February 6, 1140) was a medieval Archbishop of York. The son of a priest, he served King William II of England and King Henry I of England before his election to the see of York in 1114. Once elected, his consecration was delayed for five years while he fought attempts by the Archbishop of Canterbury to assert authority over York. Eventually, he was consecrated by the pope and allowed to return to England. While archbishop, he secured two new suffragan bishops for his province. When King Henry I died, Thurstan supported Henry's nephew Stephen of Blois as king. Thurstan also defended the northern part of England from invasion by the Scots, taking a leading part in organizing the English forces at the Battle of the Standard. Shortly before his death, Thurstan resigned from his see and took the habit of a Cluniac monk.Thurstan was the son of a canon of St Paul's in London named Anger or Auger who held the prebend of Cantlers. Another son of Anger, Audoen, was later Bishop of Évreux. Read more...
Ogilvie, the son of a wealthy Lalaird, was born into a respected Calvinist family near Keith in Banffshire, Scotland and was educated in mainland Europe where he attended a number of Catholic educational establishments, under the Benedictines at Regensburg in Germany and with the Jesuits at Olomouc and Brno in the present day Czech Republic. In the midst of the religious controversies and turmoil that engulfed the Europe of that era he decided to become a Catholic. In 1596, aged seventeen, he was received into the church at Louvain, Belgium. He joined the Society of Jesus in 1608 and was ordained a priest in Paris in 1610. After ordination he made repeated entreaties to be sent back to Scotland to minister to the few remaining Catholics in the Glasgow area (after the Scottish Reformation in 1560 it had become illegal to preach, proselytise for or otherwise endorse Catholicism). He returned to Scotland in November 1613 disguised as a soldier, and began to preach in secret, celebrating mass clandestinely in private homes. However, his ministry was to last less than a year. In 1614, he was betrayed and arrested in Glasgow and taken to jail in Paisley. He suffered terrible tortures, including being kept awake for eight days and nine nights, in an attempt to make him divulge the identities of other Catholics. Nonetheless, Ogilvie did not relent. Consequently, after a biased trial, he was convicted of high treason for refusing to accept the King's spiritual jurisdiction. On 10th March 1615, aged 36 years, John Ogilvie was paraded through the streets of Glasgow and hanged at Glasgow Cross.
His last words were "If there be here any hidden Catholics, let them pray for me but the prayers of heretics I will not have". After he was pushed from the ladder, he threw his concealed rosary beads out into the crowd. The tale is told that one of his enemies caught them and subsequently became a lifelong devout Catholic. After his execution Ogilvie's followers were rounded up and put in jail. They suffered heavy fines, but none was to receive the death penalty.
