About four years ago, I was asked to plan the White Mass for our diocese (in honor of the healthcare professionals). The Mass fell on the Feast of St. Luke. The director of pastoral services at one of the hospitals wanted to bring up a replica of a heart and a brain as well as a stethescope and the medical symbol during the offertory. My pv, who was the prelate assigned to assist, did not like the idea one bit. I dug up Redemptionis Sacramentum and he showed the director that what he wanted to do was plain wrong. He argued that the bishop seemed to not have a problem with it. We told him that the Church does not allow this. Needless to say, we put the kibosh on that one and the body parts stayed home.
Even during Papal Masses, at least the ones during the Benedictine era, have only seen bread and wine brought up. The only time that the collection, for lack of a better word, is taken up, is during the Evening Mass of the Lord’s Supper, when the Holy Father is celebrating Mass at St. John Lateran.
