P. Nicola Bux skriver hos zenit.org om hvordan presten på mange måter uttrykker møtet med det hellige når han feirer messen:
Faith in the presence of the Lord, and in particular in his Eucharistic presence, is expressed in an exemplary manner by the priest when he genuflects with profound reverence during the Holy Mass or before the Eucharist.
In the post-conciliar liturgy, these acts of devotion have been reduced to a minimum in the name of sobriety. The result is that genuflections have become a rarity, or a superficial gesture. We have become stingy with our gestures of reverence before the Lord, even though we often praise Jews and Muslims for their fervor and manner way of praying.
More than words, a genuflection manifests the humility of the priest, who knows he is only a minister, and his dignity, as he is able to render the Lord present in the sacrament. However, there are other signs of devotion.
When the priest extends his hands in prayer he is indicating the supplication of the poor and humble one. … In proceeding to the altar, the priest must be humble, not ostentatious, without indulging in looking to the right and to the left, as if he were seeking applause. Instead, he must look at Jesus; Christ crucified is present in the tabernacle, before whom he must bow. …
The reverent kiss of the altar follows and eventually the incense, the sign of the cross and the sober greeting of the faithful. Following the greeting is the penitential act, to be carried out profoundly with the eyes lowered. In the extraordinary form, the the faithful kneel, imitating the publican pleasing to the Lord. …
He will touch the holy gifts with wonder … He will bow his head over the bread and the chalice in pronouncing the consecrating words of Christ and in the invocation of the Holy Spirit (epiclesi). He will raise them separately, fixing his gaze on them in adoration and then lowering them in meditation. He will kneel twice in solemn adoration. …
After communion, silence for thanksgiving can be done standing, better than sitting, as a sign of respect, or kneeling, if it is possible, as John Paul II did to the end when he celebrated in his private chapel, with his head bowed and his hands joined. He asked that the gift received be for him a remedy for eternal life, as in the formula that accompanies the purification of the sacred vessels; many faithful do so and are an example. …
