Arcudius, de Concordia Ecclesiae Occidentalis, et Orientalis, bk. 5, chap. 55 and 56, points out the extremes to which this ceremony leads and beseeches the popes to abolish it entirely. Clement VIII did this in an Instruction, as did We in Our constitution 57, Etsi Pastoralis, sect. 6, no. 3f. It was decreed at the Synod of Zamoscia, which was studied by the Congregation of the Council as well as by the Congregation for the Propagation of the Faith, that the ceremony of consecrating the Eucharist on Holy Thursday, pouring on it a drop of the Blood and keeping it for a full year for the sick should for the future be discontinued wherever it was still in practice. Parish priests should keep the Eucharist for the sick but replace it every week or fortnight (sect. 3, de Eucharistia). The fathers of the synod of Lebanon, which We confirmed, acted in the same way (chap. 12, de Sacramento Eucharistiae, no. 24).
