And I said unto him, Sir, you know. And he said to me, These are they who came out of the great tribulation, and have washed their robes, and made them white in the blood of the Lamb.
All Commentaries on Revelation 7:14 Go To Revelation 7
George Leo Haydock
AD 1849
White in the blood of the Lamb. That is, they have been cleansed and purified from sin, by the death, merits, and grace of Christ crucified. (Witham)
The whole of this verse must be understood in a mystical sense, for we are said to make our garments white in the blood of the Lamb, when we enter into his Church by baptism, or wash away our sins by penance or martyrdom. (Calmet)
