EPISTLE Heb. 5:1-6
Brethren: Every high priest taken from among men is ordained for men in the
things that appertain to God, that he may offer up gifts and sacrifices for
sins: Who can have compassion on them that are ignorant and that err: because
he himself also is compassed with infirmity. And therefore he ought, as for the
people, so also for himself, to offer for sins. Neither doth any man take the
honour to himself, but he that is called by God, as Aaron was. So Christ also
did not glorify himself, that he might be made a high priest: but he that said
unto him: "Thou art my Son: this day have I begotten thee." As he
saith also in another place: "Thou art a priest for ever, according to the
order of Melchisedech."
GRADUAL Eccli. 44:16, 20
Behold a great priest, who pleased God in his life.
V. There was none found like to him, who kept the law of the Most
High.
Alleluia, alleluia! V. John 10:14
I am the good shepherd and I know my sheep, and mine know me. Alleluia!
GOSPEL John 10:11-16
At that time, Jesus said to the Pharisees, "I am the good
shepherd. The good shepherd giveth his life for his sheep. But the hireling and
he that is not the shepherd, whose own the sheep are not, seeth the wolf coming
and leaveth the sheep and flieth: and the wolf casteth and scattereth the sheep,
And the hireling flieth, because he is a hireling: and he hath no care for the
sheep. I am the good shepherd: and I know mine, and mine know me. As the Father
knoweth me, and I know the Father: and I lay down my life for my sheep. And
other sheep I have that are not of this fold: them also I must bring. And they
shall hear my voice: And there shall be one fold and one shepherd."
OFFERTORY ANTIPHON Ps. 20:4-5
You have placed on his head a crown of precious stones, O Lord. He asked
life of You, and You have given it to him, alleluia!
SECRET
Bless the gifts we have set apart for You, O Lord. may the prayers of Your
blessed martyr bishop, Thomas, help these offerings to win Your mercy for us.
Through our Lord . . .

2nd Day in the Octave of the Immaculate Conception
Pope Innocent XII raised it to a feast of the 2nd Class with a Common Octave in 1693.
This was about 150 years BEFORE Pope Pius IX solemnly defined it as a dogma of the faith in 1844.
Later Pope Leo XIII raised it to a feast of the 1st Class with a Vigil in 1879.
Virgin Most Pure, pray for us!

Transferred Feast of St Andrew
Since the feast of St. Andrew fell on a Sunday this year, his feast is transferred to the next day, Dec 1 in the pre-1955 Missal. His vigil would still be held on Sat, Nov 29 as usual.
If you are following the 1962 Missal, his feast disappears this year because the 1st Sunday of Advent outranks his feast. Also notice that on the 1962 Calendar, Dec 1 is a feria day. Once again they did away with a great feast and replaced it with a feria. How does this make the calendar richer? How does this show honor to one of the 12 Apostles?
This is a unique year in that 8 of the 12 Apostles' feasts fall on a Sunday. Except for the feast of Sts. Peter and Paul on June 29, all the other Apostles were skipped this year if you followed the 1962 Missal. In the pre-1955 Missal, their feasts would have trumped the Sunday (except St Andrew as explained above and St. Thomas who falls on the 4th Sunday of Advent), but the Sundays would have been commemorated along with the Proper Last Gospel of the Sunday.
St. Andrew, pray for us!
