The Roman Missal: Proper of Saints, May and June (English) 38
1[June 18. Saints Marcus and Marcellianus, Martyrs.]
2Introit. Ps. xxxvi. The salvation of the just is from the Lord: and he is their protector in the time of trouble. Ps. Be not emulous of evil-doers; nor envy them that work iniquity. Glory, &c.
3Prayer. Præsta. Grant, we beseech thee, O Almighty God, that we who celebrate the festival of thy holy martyrs, Marcus and Marcellianus, may be delivered by their intercession from all the evils which threaten us. Through our Lord, &c.
4Epistle. Romans v. 1—5. Brethren, being justified by faith, let us have peace with God, through our Lord Jesus Christ; by whom also we have access through faith into this grace, wherein we stand, and glory in the hope of the glory of the sons of God. And not only so, but we glory also in tribulations; knowing that tribulation worketh patience, and patience trial, and trial hope, and hope confoundeth not; because the charity of God is poured forth in our hearts by the Holy Ghost who is given to us.
5Gradual. The souls of the just are in the hand of God; and the torment of malice shall not touch them.—In the sight of the unwise they seem to die: but they are in peace. Alleluia, alleluia.—This is the true fraternity, which could never be broken by combat: who, by shedding their blood, followed the Lord. Alleluia.
6Gospel. St Luke xi. 47—51. At that time, Jesus said to the Scribes and Pharisees, Wo to you who build the monuments of the prophets: and your fathers killed them. Truly you bear witness that you consent to the doings of your fathers: for they indeed killed them, and you build their sepulchres. For this cause also the wisdom of God said, I will send to them prophets and apostles, and some of them they will kill and persecute. That the blood of all the prophets, which was shed from the foundation of the world, may be required of this generation; from the blood of Abel unto the blood of Zacharias, who was slain between the altar and the temple. Yea, I say to you, it shall be required of this generation.
8Secret. Sanctify, O Lord, the offerings devoted to thee, and by the intercession of thy holy martyrs, Marcus and Marcellianus, by the same, look favourably upon us. Through our Lord, &c.
10Postcom. Salutaris tui. Filled with the gift of thy salvation, we humbly beseech thee, O Lord, that by the intercession of thy holy martyrs, Marcus and Marcellianus, we may be renewed by the effect of that at the taste of which we rejoice. Through our Lord, &c.
