Pastoral Note #2141995
The Rite of Blessing Automobiles
Among the many blessings of the Second Vatican Council, the newly revised Book of Blessings ranks as one of the newest but most promising. Yet by its very nature it will require frequent revision, updating and additions in order to bring it into greater conformity with the other liturgical books of the Roman Rite and make it more fully adapted to the needs of the local community.
Blessings of Automobiles are among the most frequently requested blessings today, yet the rite provided in the new Book of Blessings is woefully inadequate. Please be advised, therefore, that in addition to the Longer Rite and the Shorter Rite provided in the Book of Blessings, there exists a third option: the Rite of Blessing Automobiles by Total Immersion.
The complete rite is being prepared by the Liturgical Commission of the Archdiocese of Detroit, in recognition of the fact that this will spring more fully out of their local culture. The following norms should be regarded as provisional in nature, and will be superseded by the publication of the complete rite.
The use of holy water in the Church’s life is always intended to remind us of Baptism. Hence, the total immersion of the automobile or other vehicle to be blessed is the fuller sign, an effective symbol manifesting the desire of the Church that the entirety of our lives be immersed in the Mystery of Christ.
Any parish faith community can provide itself with an immersion tank for the automobile, constructed under the careful, expert supervision of the Diocesan Liturgical Commission. The tank should be sufficiently deep that total immersion is possible, thus providing for the fullness of the sign. It is recognized, however, that practical difficulties (the presentation by its sponsors of a Mack Truck, for example) may make total immersion impossible, in which case the minister of blessing may resort to infusion (pouring). Care should be taken, however, that with proper catechesis the Faithful understand the value and significance of the fuller celebration of the sign.
The automobile should not be driven into the pool by ramp. The integrity of the sign requires that the automobile be lowered into the blessed water, thereby signifying that one cannot attain to a state of blessedness by one’s own unaided effort. Necessarily, the car will be lowered into the water by cable. There should, however, be only one cable, to avoid unnecessary multiplication of symbols. Care should be taken that the faith community resist the merely pragmatic sort of reasoning which has resulted in such appalling abuses as several crucifixes in the sanctuary at the Veneration of the Cross on Good Friday, multiple chalices on the altar, holy water stoups at each door of the church, and many people in the congregation on Sunday – all of which are signs that the liturgical renewal has not yet born fruit in a parish. One bread, one body/one car, one cable.
It is best that the car be immersed three separate times, at the invocation of each Person of the Trinity. For serious reasons, however, the minister of blessing may deem one immersion to be sufficient. It is fitting that representatives of the community, especially those who will be served by the vehicle, be seated in the car as it is immersed. The Prayer of Blessing is read before the immersion, by a Priest or Deacon with hands outstretched over the vehicle; by a layman or a lay lady with hands joined. In either case the minister of blessing will almost certainly require the assistance of three hefty altar servers capable of holding up the new Book of Blessings while the prayer is read.
As soon as the new rite for the blessing of automobiles and other vehicles is approved, along with the General Instruction of the Blessing of Automobiles, the Scriptural Reflection, and the Pastoral Reflection, the norms contained therein will supersede the norms contained herein. All things to the contrary notwithstanding. Until then, these norms will be regarded as having the force of anything contained in the Book of Blessings, with the texts already provided in the Book of Blessings:
Introduction and Greeting
Reading from Scripture
Intercessions/Prayer of Blessing
Immersion of the Vehicle in Blessed Water
Placing of Symbols
In certain situations the rite may be abridged if local circumstances suggest difficulty with the implementation pf the fuller rite (i.e., northern climes where the water might freeze; southern climes where it might evaporate; other places where the congregation might lose interest and just wander away…).
