​AN ANCIENT SACRED SCRIPTURE MEDITATION FROM THE PROPHECY OF ZECHARI'AH,
​OF THE TRIBE OF LEVI, AT THE BIRTH OF HIS SON, ST. JOHN THE BAPTIST:
​

THE BENEDICTUS
​
​

[Latin]
​
BENEDICTUS Dominus Deus Israel, *
quia visitavit, et fecit redemptionem plebis suae:
Et erexit cornu salutis nobis *
in domo David pueri sui.
Sicut locutus est per os sanctorum, 
​qui a saeculo sunt, prophetarum eius:
Salutem ex inimicis nostris, *
et de manu omnium qui oderunt nos:
Ad faciendam misericordiam cum patribus nostris: *
et memorari testamenti sui sancti:
Iusiurandum, quod iuravit ad Abraham patrem nostrum, *
daturum se nobis;
Ut sine timore, de manu inimicorum nostrorum liberati, *
serviamus illi.
In sanctitate et iustitia coram ipso, *
omnibus diebus nostris.
Et tu puer, propheta Altissimi vocaberis: *
praeibis enim ante faciem Domini parare vias eius:
Ad dandam scientiam salutis plebi eius: *
in remissionem peccatorum eorum:
Per viscera misericordiae Dei nostri: *
in quibus visitabit nos, oriens ex alto:
Illuminare his qui in tenebris et in umbra
​mortis sedent: *
ad dirigendos pedes nostros in viam pacis.

[LUKE 1:68-79, Vulgata]

​Blessed be the Lord God of Israel,
for he has visited and redeemed his people,
and has raised up a horn of salvation for us
in the house of his servant David,
as he spoke by the mouth
of his holy prophets from of old,
that we should be saved from our enemies,
and from the hand of all who hate us;
to perform the mercy promised to our fathers,
and to remember his holy covenant,
the oath which he swore to our father Abraham,
to grant us
that we, being delivered from the hand of our enemies,
might serve him without fear,
in holiness and righteousness before him
​all the days of our life.
And you, child, will be called the prophet of the Most High;
for you will go before the Lord to prepare his ways,
to give knowledge of salvation to his people
in the forgiveness of their sins,
through the tender mercy of our God,
when the day shall dawn upon us from on high
to give light to those who sit in darkness and in the shadow of death,
to guide our feet into the way of peace.”

[LUKE 1:68-79, RSVCE]
