1. Reasons Why the Ancient Saints Worshiped on Sunday.--But Sunday is the day on which we all hold our common assembly, because it is the first day on which God, when he changed the darkness and matter, made the world; and Jesus Christ our Savior on the same day rose from the dead; for the day before that of Saturn he was crucified, and on the day after it, which is Sunday, he appeared to his apostles and disciples and taught them these things which we have given to you also for your consideration.--Justin Martyr.
2. Description of Christian Public Worship in the Second Century.--On the day which is called Sunday there is an assembly in the same of all who live in cities or in country districts; and the records of the apostles, or the writings of the prophets, are read as long as we have time. Then the reader concludes, and the president verbally instructs and exhorts us to the imitation of these excellent things. Then we all rise together and offer up our prayers. And, as I said before, when we have concluded our prayer, bread is brought, and wine and water, and the president in like manner offers up prayers and thanksgivings with all his strength, and the people give their assent by saying Amen; and there is a distribution and a partaking by every one of the eucharistic elements [the sacrament,] and to those who are not present they are sent by the hands of the deacons. And such as are in prosperous circumstances, and wish to do so, give what they will, each according to his choice; and what is collected is placed in the hands of the president, who assists the orphans and widows, and such as through sickness or any other cause are in want; and to those who are in bonds, and to strangers from afar, and, in a word, to all who are in need, he is a protector.--Justin Martyr.
3. Baptism a Symbol of Burial and Resurrection.--In writing to the saints of Rome, Paul says: "Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death? Therefore { 136} we are _buried_ with him by baptism into death; that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life. For if we have been _planted_ together in the likeness of his death, we shall be also in the likeness of his resurrection." (Rom. vi:3-5.) In writing to the saints of Colosse, the same apostle reminds them that they had been "_Buried_ with him [Christ] in baptism, wherein also ye are risen with him through the faith of the operation of God who hath raised him from the dead." (Col. ii: 12.)
