There are four elavations which are called for by the rubrics at Mass. At the preparation of the gifts, the elements are "raised slightly above the altar." At the Consecration, the consecrated elements are "shown to the people."
During the Doxology, the chalice and paten are "elevated." At the Ecce Agnus Dei, the consecrated host over a paten or chalice is "held before the people." The differences in the rubrics for each elevation are dictated by the meaning and purpose of each elevation and should be carefully respected.
