When it is said
Today the 40-day blessing often takes place on a Sunday, so the whole parish can share the joy of welcoming the new baby.
The priest makes the sign of the cross over the baby, then says this prayer over mother and child together.

Where it comes from
It opens the prayers for a mother 40 days after a birth in the Book of Needs, the priest’s book of services for life’s big moments. No writer is named. The Slavonic Book of Needs carries these prayers, and so does the Greek edition that Jacques Goar printed in Paris in 1647.

Why 40 days?
The number comes from the Law of Moses, which kept a mother away from the sanctuary for 40 days after the birth of a son (Leviticus 12:2-4). Mary and Joseph kept that law with the infant Jesus (Luke 2:22). The Church keeps the same 40 days for a baby girl as for a boy.

What the words mean
“Cleanse her from every sin”
The prayer asks God to cleanse the mother from every sin and impurity, so that she may receive the holy Mysteries, the Church’s name for Holy Communion. The priest asks God to cleanse him in the same way, in a quiet prayer at the start of every baptism.

The Scripture in it
Through Him all things were made, and without Him nothing was made that has been made.

In Church Slavonic
Господи Боже Вседержителю, Отче Господа нашего Иисуса Христа,
все естество словесное же и безсловесное словом Твоим создавый,
и вся от несущих во еже быти приведый,
Тебе молимся, и Тебе просим:
Твоею волею спасл еси рабу Твою, имярек,
очисти от всякаго греха, и от всякия скверны,
приходящую ко святей Твоей Церкви,
да неосужденно сподобится причаститися святых Твоих Таин.
И от нея рожденное отроча благослови, возрасти, освяти, вразуми, уцеломудри, удобромудрстви:
яко Ты привел еси е, и показал еси ему свет чувственный,
да и умнаго сподобится света, во время еже определил еси,
и сопричтется святому Твоему стаду,
Единородным Твоим Сыном, с Нимже благословен еси,
с Пресвятым и Благим, и Животворящим Твоим Духом,
ныне и присно, и во веки веков, аминь.
