This study examines the collects assigned to the Sundays and major feasts of the proper seasons in the ordinary and extraordinary forms of the Roman rite. The Latin collects assigned to each day in the typical editions of the respective missals are compared and contrasted both with their respective sources and with one another. Pertinent discussions and decisions of the Consilium study groups responsible for the post-Vatican II revisions of the liturgical calendar and Mass collects are also presented and considered. The goal of the study is to determine whether the two sets of collects present the same picture of the human situation, approach God in the same way, seek the same things from him, and, where they do not, to identify significant changes in theological and/or spiritual emphases.
