What are the words of the Our Father?

Our Father, who art in heaven, hallowed be thy name,
thy kingdom come,
thy will be done
on earth as it is in heaven.
Give us this day our daily bread,
and forgive us our trespasses,
as we forgive those who trespass against us;
and lead us not into temptation,
but deliver us from evil.
For thine is the kingdom and the power and the glory forever. Amen.

In Latin:

Pater noster, qui es in caelis; sanctificetur nomen tuum;
adveniat regnum tuum,
fiat voluntas tua,
sicut in caelo et in terra.
Panem nostrum quotidianum da nobis hodie;
et dimitte nobis debita nostra,
sicut et nos dimittimus debitoribus nostris;
et ne nos inducas in tentationem;
sed libera nos a malo.
Quia tuum est regnum, et potestas, et gloria in saecula. Amen.

The Our Father is the only prayer that Jesus himself taught his disciples
(Mt 6:9-13; Lk 11:2-4). That is why the Our Father is also called “the Lord’s Prayer”. Christians of all Christian denominations pray it daily, both in the liturgy and privately. The conclusion, “For thine is the kingdom … ”
is mentioned as early as the “Teaching of the Twelve Apostles”
(Didache, ca. A.D. 150), and so it can be added to the Our Father.

How did the Our Father come about?

The Our Father came about at the request of one of Jesus’ disciples, who saw his Master praying and wanted to learn from Jesus himself how to pray correctly.
