text: Tridentinus, your reply side stepped my question: "...please elaborate on diaconal role in Tridentine ritual. Your description does not match my recollection of the missa solemnis. Much intrigued!"
  
  I am not looking for an argument here. Quite the opposite, I would treasure any evidence of a diaconal role in the Offertory in the Trindentine liturgy. Historically, in the Byzantine liturgy, the deacon received the bread brought to Church by the faithful before the Divine Liturgy began, and was largely responsible for the Great Entrance (originally a procession from the back of, or outside of, the Church were the gifts were assembled), the primary offertory event in the Byzantine liturgy. 
  
  You say the deacon offered the chalice with the priest and say the Offerimus tibi with the priest. Please point me to this ritual. Which version of the missa?
