twilight". In Psalm 92, which is a prayer concerning the observance of the Sabbath, the prophet David writes "It is good to give thanks to the Lord, to sing praises to your name, O Most High; to declare your steadfast love in the morning, and your faithfulness by night" (cf. ). Church father Eusebius of Caesarea thus declared: "For it is surely no small sign of God’s power that throughout the whole world in the churches of God at the morning rising of the sun and at the evening hours, hymns, praises, and truly divine delights are offered to God. God’s delights are indeed the hymns sent up everywhere on earth in his Church at the times of morning and evening." The first miracle of the Apostles, the healing of the crippled man on the temple steps, occurred because Peter and John went to the Temple to pray (Acts 3:1). Since the Apostles were originally Jews, see Jewish Christians, the concept of fixed prayer times, as well as services therefore which differed from weekday to Sabbath to holy day, were familiar to them. Pliny the Younger (63 - ca. 113), who was not a Christian himself, mentions not only fixed prayer times by believers, but also specific services—other than the Eucharist—assigned to those times: "They met on a stated day before it was light, and addressed a form of prayer to Christ, as to a divinity ... after which it was their custom to separate, and then reassemble, to eat in common a harmless meal." The real evolution of the Christian service in the first century is shrouded in mystery. By the second and third centuries, such Church Fathers as Clement of Alexandria, Origen, and Tertullian wrote of formalised, regular services: the practice of Morning and Evening Prayer, and prayers at the third hour of the day (terce), the sixth hour of the day (sext), and the ninth hour of the day (none). With reference to the Jewish practices, it is surely no coincidence that these major hours of prayer correspond to the first and last hour of the conventional day, and that on Sundays (corresponding to the Sabbath in Christianity), the services are more complex and longer (involving twice as many services if one counts the Eucharist and the afternoon service). Similarly, the liturgical year from Christmas via Easter to Pentecost covers roughly five months, the other seven having
