Justin Martyr was a Christian catechist living in Rome who was martyred, along with several of his students, in the mid-second century. His First Apology, written in the style of a classical speech of defense, was addressed to the household of the non-Christian Emperor Antoninus Pius, defending the new faith and arguing for their conversion to Christianity.
Worship during the second and third centuries continued to follow the course set by New Testament liturgical traditions. Consequently, the discussion of worship during this period centered on the significance of baptism and of the Eucharist, understood in its full content of the service of Word and of the Lord’s table.
The result of the writings of the Apologists was to dignify Christianity and give it a place as a reasoned system of thought, not merely as a passing spiritual fad.
