Christmas Eve - The Lord is Coming!

Introit for the Mass on Christmas Eve day:

Hodie scietis, quia veniet Dominus, et salvabit nos:
et mane videbitis gloriam eius.

V. Domini est terra, et plenitudo eius:
orbis terrarum, et universi qui habitant in eo.

Today you shall know that the Lord is coming, and that He

shall save us: and in the morning you shall see His glory.

V. The earth is the Lord’s, and its fullness:
the whole world, and all who dwell in it.
