Blessing for Any Thing: a Computer Blessing from the Roman Ritual
Also called Benedictio ad omnia, blessing for a new laptop, blessing of machines, Catholic blessing of tools
The old Roman Ritual includes a short blessing for any object that has no special form of its own, and its later editions added blessings for telegraphs, aeroplanes and machinery. This page explains that history and gives a simple lay prayer of blessing for a new computer, phone or tool.

The working
Set the new computer, phone or tool on a clean table, switched off. Place a cross or holy card beside it if you have one.
Make the sign of the cross and say: Our help is in the name of the Lord, who made heaven and earth.
Pray in your own words, in the spirit of the old blessing for any thing: Lord, bless this machine, made by human skill. Let it serve good work, keep it from harm, and let all who use it give you thanks.
Ask that it never be used to hurt anyone, and name the good work you intend to do with it.
If a priest or deacon is blessing it, he may sprinkle holy water. Ask him to sprinkle the box, the case lid or the air above it, not the screen, keys or ports.
Close with the Our Father and the sign of the cross, then switch the machine on and begin.
Take care: Holy water is still water: never sprinkle it on screens, keyboards, ports or vents, and keep the device switched off and unplugged during any blessing. Respect the difference between a priest's liturgical blessing and a lay prayer.
Versions across time and place
i
Benedictio ad omnia, the priest's blessing for anything
Rituale Romanum · 1614 to 1964 editions
A short Latin form a priest could use for any created thing with no blessing of its own. He asks God's blessing on the object so that whoever uses it with thanks receives health of body and protection of soul, then sprinkles holy water.
Recorded in: Rituale Romanum, Latin editions (for example 1917 and 1952)
ii
Blessings of telegraphs, aeroplanes and machinery
Roman Ritual, English edition · Weller translation, 1946
By the twentieth century the Ritual had added named blessings for new technology, including the telegraph, the aeroplane, the motor car and any mechanical object. Parishes used them to bless factory machines, fire engines and cars.
Recorded in: Philip T. Weller (trans.), The Roman Ritual, Volume III: Blessings (1946)
iii
The modern Book of Blessings
Post-Vatican II Catholic · 1984 Latin, 1989 English
The revised book groups blessings by kind and includes prayers for tools and technical installations and for means of transport. It allows lay people to lead some blessings with a simpler form that asks for God's blessing rather than giving it.
Recorded in: De Benedictionibus (1984); Book of Blessings, USCCB (1989)
History
The Rituale Romanum, issued under Pope Paul V in 1614, gathered the Church's rites for priests outside the Mass. Alongside baptism and the sick, it held blessings for houses, fields, food and ships. One short form, the benedictio ad omnia, let a priest bless any object that lacked a form of its own. Later editions added blessings for railways, telegraphs, electric dynamos, aeroplanes and cars, as new machines entered daily life.
No blessing in these books mentions computers, which did not yet exist. The modern Book of Blessings of 1984 offers prayers for tools and technical equipment, and many priests today bless laptops, servers and newsrooms with them. The lay prayer on this page is our adaptation, written in the spirit of the blessing for any thing. A priest's blessing follows the Church's own book, and a lay person asks a blessing rather than gives one.
