The Orban is a round piece of bread baked at church; it must be baked by a deacon while reading the entire Book of Psalms as the Psalms are full of important prophesies about Lord Jesus.
The Gospel of John presents Jesus as saying: "Unless you eat the flesh of the Son of Man and drink His blood you have no life in you … he who eats My flesh and drinks my blood abides in Me and I in him" (6:53-56).
St. Paul reminded the Corinthian Christians of Jesus' Words at the Last supper and concluded from that: " Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of profaning the Body and Blood of the Lord" (1 Corinthians 11:27).
The Eucharistic Bread is baked in an oven built near the sanctuary (in a room called Bethlehem such as the picture below, which means in Hebrew "House of bread"). The Offering Bread is a small round loaf of bread stamped with the Cross in the middle that represents the Lord with five holes around it as they represent the five Holy Wounds of Christ in addition of 12 cross representing the Holy Apostles.
The Eucharistic Bread is one of the two visible elements constituting the Eucharistic Sacrament, the other element being the Eucharistic wine which is not an alcoholic product and it is also diluted by water representing the blood and water that came out of Jesus's side.
The Bread is leavened (referring to our sins) and baked (referring to the salvation we received by the passions of Christ that he had suffered on our behalf), unsalted and made of the finest wheat flour.
The only ingredients in the Orban are white flour, water, and yeast. Simply put, the Holy Traditions mentioned nothing else!!
Our Orban servants meet four hours prior to any church Liturgy prayer to prepare the Oblation Bread.
