In case you've been wondering, yes, today is the feast my heavenly patron, the Holy Apostle and Evangelist Matthew

The Epistle for St. Matthew's Day:

For I think that God has displayed us, the apostles, last, as men condemned to death; for we have been made a spectacle to the world, both to angels and to men. We are fools for Christ's sake, but you are wise in Christ! We are weak, but you are strong! You are distinguished, but we are dishonored! To the present hour we both hunger and thirst, and we are poorly clothed, and beaten, and homeless. And we labor, working with our own hands. Being reviled, we bless; being persecuted, we endure; being defamed, we entreat. We have been made as the filth of the world, the offscouring of all things until now. I do not write these things to shame you, but as my beloved children I warn you. For though you might have ten thousand instructors in Christ, yet you do not have many fathers; for in Christ Jesus I have begotten you through the gospel. Therefore I urge you, imitate me. (1 Corinthians 4:9-16)

The Gospel for St. Matthew's Day:

As Jesus passed on from there, He saw a man named Matthew sitting at the tax office. And He said to him, "Follow Me." So he arose and followed Him. Now it happened, as Jesus sat at the table in the house, that behold, many tax collectors and sinners came and sat down with Him and His disciples. And when the Pharisees saw it, they said to His disciples, "Why does your Teacher eat with tax collectors and sinners?" When Jesus heard that, He said to them, "Those who are well have no need of a physician, but those who are sick. But go and learn what this means: 'I desire mercy and not sacrifice.' For I did not come to call the righteous, but sinners, to repentance. (Matthew 9:9-13)

Troparion (In Tone 3):

With zeal, you followed Christ the Master,
who in His goodness, appeared on earth to mankind.
Summoning you from the custom house,
He revealed you as a chosen apostle:
the proclaimer of the the Gospel to the whole world!
Therefore, divinely eloquent Matthew,
we honor your precious memory!
Entreat merciful God that He may grant our souls remission of transgressions.

Kontakion (In Tone 4):

Casting aside the bonds of the custom house for the yoke of justice,
you were revealed as an excellent merchant, rich in wisdom from on high.
You proclaimed the word of truth
and roused the souls of the slothful
by writing of the hour of Judgment.
