In terms of the traditional Roman Rite, liturgically-speaking, one’s posture should be oriented to the Blessed Sacrament when exposed. So, it depends on whether one is talking about a more-traditional view or not.
Follow-up: Exposition During Way of the Cross [03-15-2005]
With respect to our comments regarding the inappropriateness of making the Way of the Cross before the Blessed Sacrament exposed (see March 1), a Franciscan friar “begged to differ” and described his order’s practice.
“In some of our friary churches,” he writes, “we have perpetual adoration and for almost 15 years now we have had the Stations while the Blessed Sacrament is exposed. We have been following the rubrics which, [by] my understanding, is approved by the Church. When the Blessed Sacrament is exposed the priest remains stationary, standing in front of the Blessed Sacrament, and only the cross and candle bearers, if any, move from station to station. The people remain in their places and genuflect at their places. They may watch the cross bearer as he goes from station to station, but most people focus on the Blessed Sacrament exposed on the altar. At the end there is no blessing given and the priest and acolytes exit in silence.”
