text: Justin Martyr's First Apology Chapter 66 circa 155AD. 
  Just because it is dated circa 155AD does not mean that it dates from that time. St Justin was describing something which was a regular happening in the middle of the Second Century. All the basic elements of the Mass or Divine Liturgy are present: 1) Taking bread and wine, 2) Giving thanks, 3) Blessing, consecration, becoming the flesh and blood of Christ, 4) Remembrance, anamnesis, 5) Communion.
  This follows pretty much St Paul's description of the Eucharist in 1 Corinthians 11:23 et seq, and the narratives of the Last Supper in the Synoptic Gospels.
  Further evidence regarding the sacrificial nature of the Mass can be obtained from the Didache ca 70AD, Clement of Rome ca 80AD,  Ignatius of Antioch ca 110AD and Irenaeus ca 189AD.
  There, a bit more than the shred of evidence you asked for.
