According to the "Liber Pontificalis", he passed the following three ordinances: (1) that none but sacred ministers are allowed to touch the sacred vessels; (2) that bishops who have been summoned to the Holy See shall, upon their return, not be received by their diocese except on presenting Apostolic letters; (3) that after the Preface in the Mass the priest shall recite the Sanctus with the people.
Period: 125 to 136
Reign of Pope St. Telesphorus
Telesphorus is mentioned as one of the Roman bishops who always celebrated Easter on Sunday, without, however, abandoning church fellowship with those communities that did not follow this custom.
Period: 136 to 140
Reign of Pope St. Hyginus
The "Liber Pontificalis" also relates that this pope organized the hierarchy and established the order of ecclesiastical precedence. This general observation recurs also in the biography of Pope Hormisdas; it has no historical value, and according to Duchesne, the writer probably referred to the lower orders of the clergy.
Period: 140 to 155
Reign of Pope St. Pius I
The "Liber Pontificalis" (ed. Duchesne, I, 132) says the father of Pius was Rufinus, and makes him a native of Aquileia
Period: 155 to 166
Reign of Pope St. Anicetus
While Anicetus was Pope, St. Polycarp, then in extreme old age, came to confer with him (160-162) about the Paschal controversy; Polycarp and others in the East celebrating the feast on the fourteenth of the month of Nisan, no matter on what day of the week it fell; whereas in Rome it was always observed on Sunday, and the day of the Lord's death on Friday.

The letter which Soter had written in the name of his church is lost, though Harnack and others have attempted to identify it with the so-called "Second Epistle of Clement"
Period: 175 to
Reign of Pope St. Eleutherius
From his contemporary Hegesippus we learn that he was a deacon of the Roman Church under Pope Anicetus (c. 154-164), and evidently remained so under St. Soter, the following pope, whom he succeeded about 174.
Death of St. Irenaeus of Lyons
Death of St. Gregory of Neocaesarea
Death of Pope St. Zephyrinus
Period: 217 to 222
Reign of Pope St. Callistus
In fact the Church of St. Callistus is close by, containing a well into which legend says his body was thrown, and this is probably the church he built, rather than the more famous basilica.
Period: 222 to 230
Reign of Pope St. Urban
The dissension produced in the Roman Church by Hippolytus continued to exist during Urban's pontificate. Hippolytus and his adherents persisted in schism; it was probably during the reign of Urban that Hippolytus wrote his "Philosophumena", in which he attacked Pope Callistus severely.
Period: 230 to 235
Reign of St. Pontian
The schism of Hippolytus continued during his episcopate; towards the end of his pontificate there was a reconciliation between the schismatic party and its leader with the Roman bishop.
Period: 235 to 236
Reign of St. Anterus
Reign lasts forty days
Period: 236 to 250

Council of Cartage
Treaty 'On the Unity of the Church' is written by St. Cyprian
Period: 251 to 253
Reign of Pope St. Cornelius
About the beginning of March, 251 the persecution slackened, owing to the absence of the emperor, against whom two rivals had arisen. It was possible to assemble sixteen bishops at Rome, and Cornelius was elected though against his will, "by the judgment of God and of Christ, by the testimony of almost all the clergy, by the vote of the people then present, by the consent of aged priests and of good men”
Period: 253 to 254
Reign of Pope St. Lucius I
The persecution of the Church under the Emperor Gallus, during which Cornelius had been banished, still went on. Lucius also was sent into exile soon after his consecration, but in a short time, presumably when Valerian was made emperor, he was allowed to return to his flock.
Period: 254 to 257
Reign of St. Stephen I
Most of what we know regarding Pope Stephen is connected directly or indirectly with the severe teachings of the heretic Novatus.
Period: 257 to
Reign of Pope St. Sixtus II
During the pontificate of his predecessor, St. Stephen, a sharp dispute had arisen between Rome and the African and Asiatic Churches, concerning the rebaptism of heretics, which had threatened to end in a complete rupture between Rome and the Churches of Africa and Asia Minor.
Period: 275 to
Reign of Pope St. Eutychian
The rite for blessing the produce of the fields, ascribed to him by the "Liber Pontificalis", undoubtedly belongs to a later period. The statement also that he promulgated rules for the burial of martyrs and buried many of them with his own hands, has but slight claim to acceptance.

Reign of Pope St. Dionysius
It was not until the persecution had begun to subside that Dionysius was raised (22 July, 259) to the office of Bishop of Rome. Some months later the Emperor Gallienus issued his edict of toleration, which brought the persecution to an end and gave a legal existence to the Church.
Period: to 304
Reign of Pope St. Marcellinus I
According to the "Liber Pontificalis" he was a Roman, son of a certain Projectus. The Liberian Catalogue of popes gives 30 June as the day of his election, and the years 296-304 as the time of his pontificate.
Period: to 274
