Baptism

In baptism, the white cloth symbolizes the Sanctifying Grace we received from Christ. It is the wedding garment that we should always wear until we reach the wedding banquet in heaven. You can take off this wedding garment by mortal sin. You will be thrown into the lake of fire if you will be found not wearing that cloth.
Galatians 3:27
For as many of you as have been baptized in Christ have become clothed with Christ.
Revelation 16:15
“Look, I come like a thief! Blessed is the one who stays awake and remains clothed, so as not to go naked and be shamefully exposed.”
