THE COLLECT.
O God, whose blessed Son was manifested that he might destroy the works of the devil, and make us the sons of God, and heirs of eternal life: Grant us, we beseech thee, that, having this hope, we may purify ourselves, even as he is pure; that, when he shall appear again with power and great glory, we may be made like unto him in his eternal and glorious kingdom; where with thee, O Father, and thee, O Holy Ghost, he liveth and reigneth, ever one God, world without end. Amen.

THE EPISTLE. 1 S. John 3. 1-8
BEHOLD, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew him not. Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is. And every man that hath this hope in him purifieth himself, even as he is pure. Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law. And ye know that he was manifested to take away our sins; and in him is no sin. Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither known him. Little children, let no man deceive you: he that doeth righteousness is righteous, even as he is righteous. He that committeth sin is of the devil: for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.

THE GOSPEL. S. Matth. 24. 23-31
THEN if any man shall say unto you, Lo, here is Christ, or there; believe it not. For there shall arise false Christs, and false prophets, and shall show great signs and wonders; insomuch that (if it were possible) they shall deceive the very elect. Behold, I have told you before. Wherefore if they shall say unto you, Behold, he is in the desert; go not forth: Behold, he is in the secret chambers; believe it not. For as the lightning cometh out of the east, and shineth even unto the west; so shall also the coming of the Son of Man be. For wheresoever the carcase is, there will the eagles be gathered together. Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken. And then shall appear the sign of the Son of Man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of Man coming in the clouds of heaven, with power and great glory. And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.
