There’s a modern day mystic from Bolivia named Catalina Rivas who claims to have private revelations from Jesus and Mary. Mary, the Mother of God, walks Catalina through the Mass, and this is what she says about Offertory.
A moment later the Offertory arrived, and the Holy Virgin said: “Pray like this: Lord, I offer all that I am, all that I have, all that I can do. I put everything into Your Hands. Build it up, Lord, with the little thing that I am. By the merits of Your Son, transform me, God Almighty. I petition You for my family, for my benefactors, for each member of our Apostolate, for all the people who fight against us, for those who commend themselves to my poor prayers. Teach me to lay down my heart as if on the ground before them so that their walk may be less severe. This is how the saints prayed; this is how I want all of you to do it.”
