All, therefore, were glorified and magnified, not through themselves or their own works or the righteous actions which they did, but through his will. And so we, having been called through his will in Christ Jesus, are not justified through ourselves or through our wisdom or understanding or piety or works, which we have done in holiness of heart, but through faith, by which the almighty God has justified all who have existed from the beginning, to whom be the glory for ever and ever. Amen.1 Clement 32:3-4
Instead of consuming their leisure hours in vacant idleness, or deriving their chief amusement from boisterous merriment, the recital of tales of superstition, or the chanting of the profane songs of the heathen, they passed their hours of repose in rational and enlivening pursuits; found pleasure in enlarging their religious knowledge, and entertainment in songs that were dedicated to the praise of God.The Antiquities of the Christian Church
For many ancient Romans the marital union remained permanent, even in the face of the death of a spouse. The eternal union would survive deathRemarriage in Early Christianity, Eerdmans, 38
they changed the day of rest from the seventh to the first day of the week. The Jewish Sabbath was the logical culmination of the creating work of God, who rested on the seventh day, but the first (or eighth) day symbolized the beginning of the new creation that had been established and fulfilled in Christ.God Has Spoken, 80
On that day he ordered the Galatian and Corinthian Christians to make, no doubt in connection with divine service, their weekly contributions to charitable objects according to their ability. It appears, therefore, from the New Testament itself, that Sunday was observed as a day of worship, and in special commemoration of the Resurrection, whereby the work of redemption was finished.https://ccel.org/ccel/schaff/hcc1/hcc1.i.IX.57.html
The universal and uncontradicted Sunday observance in the second century can only be explained by the fact that it had its roots in apostolic practice. Such observance is the more to be appreciated as it had no support in civil legislation before the age of Constantine, and must have been connected with many inconveniences, considering the lowly social condition of the majority of Christians and their dependence upon their heathen masters and employers. Sunday thus became, by an easy and natural transformation, the Christian Sabbath or weekly day of rest, at once answering the typical import of the Jewish Sabbath, and itself forming in turn a type of the eternal rest of the people of God in the heavenly Canaan.https://ccel.org/ccel/schaff/hcc1/hcc1.i.IX.57.html
In the gospel dispensation the Sabbath is not a degradation, but an elevation, of the week days to a higher plane, looking to the consecration of all time and all work. It is not a legal ceremonial bondage, but rather a precious gift of grace, a privilege, a holy rest in God in the midst of the unrest of the world, a day of spiritual refreshing in communion with God and in the fellowship of the saints, a foretaste and pledge of the never-ending Sabbath in heaven.https://ccel.org/ccel/schaff/hcc1/hcc1.i.IX.57.html
we cannot expect the earliest Christians to have the same clarity on the issue of sola fide as the Reformers. The emphasis we find among them on topics like good works and merit lacks the clarity of the later discussions, but a sympathetic reading doesn't posit a contradiction between them and the Reformers. True faith results in good works, and the term "merit" in the early fathers may designate the reward given instead of being interpreted to say that one earns salvation.Sola Fide, 23
O the sweet exchange, O the incomprehensible work of God, O the unexpected blessings, that the sinfulness of many should be hidden in one righteous man, while the righteousness of one should justify many sinners.Epistle to Diognetus, 9.5
