“They did not care about circumcision and neither do we. They did not care about observing Sabbaths, nor do we. They did not avoid certain kinds of food, neither did they regard the other distinctions which Moses first delivered to their posterity to be observed as symbols; nor do Christians of the present day do such things.” -Church History 1:4:8 (Written 312 A.D.)

“The day of Christ’s light.. was the day of His resurrection from the dead, which they say is the one and only truly holy day and the Lord’s day, and is better than any number of days as we ordinarily understand them, better than the days set apart by the Mosaic law for feasts, new moons, and Sabbaths, which the apostle Paul teaches are the shadow of days and not days in reality.” -Proof of the Gospel 4:16:186 (Written 319 A.D.)

Clement also, who was appointed third bishop of the church at Rome, was, as Paul testifies, his co-laborer and fellow-soldier (Phil. 4:3).” -Church History 3:4:9-10 (Written 312 A.D.)

“The holy Apostles and disciples of the Savior were scattered throughout the whole world.  Thomas, as tradition holds, received Parthia (modern Iran) by lot. Andrew, Scythia (Eurasia). John, Asia (Turkey), busying himself among the people there until he died at Ephesus. Peter preached to the Jews of the diaspora in Pontus and Galatia… and at last, having come to Rome, he was crucified head downwards, which he himself thought was fitting to suffer. Is it necessary to say anything of Paul, who. . in the time of Nero was martyred in Rome?” -Ecclesiastical History 3:1:1 (Written in 312 A.D.)
