The Offertory is that part of the Mass in which the unconsecrated bread and wine are offered to God.

the offertory. this is when the congregation bring up the bread and wine. REMEMBER IT IS NOT JESUS' BODY AND BLOOD TILL AFTER THE OFFERTORY

it is when you receive the body and blood of christ

There is no specific act of reverence called for during the offertory, which ends with the people standing asking God to accept the offering on the altar. Then the priest prays the Offertory prayer. So if you are asked for the act of reverence, I suppose it would be "standing".

The offertory is important to today's church as it allows worshippers to give back to the church and support its mission and ministries. It also serves as a way for individuals to express their gratitude to God for the blessings they have received. Additionally, the offertory helps fund the church's operational costs and charitable activities.
