Let us come with confidence to the throne of grace, that we may obtain mercy and find grace in seasonable aid. Ps. My heart hath uttered a good word: I speak my works to the King. ℣. Glory be to the Father.
Verse 16. Let us often contemplate Jesus Christ on his two thrones, that of his mercy, and that of his justice; of his mercy, where at present he is seated as our compassionate high priest, to bestow on us the riches of his grace; of his justice, where he will one day sit as judge, to examine most rigorously both our faith and our practice. Our separated brethren pretend to prove from this text that we need no help of saints to obtain any favour. But by this argument they may as well take away the helps and prayers of the living for one another. For we do not require the help of either the saints in heaven, or of our brethren on earth, through any mistrust of God’s mercy, but on account of our own unworthiness, convinced that the prayer of a just man availeth more with Him, than the desire of a grievous sinner; and of a number making intercession together, rather than of one alone. This they cannot deny, except they deny the holy Scriptures. Neither do we come less to Him, or with less confidence, when we come accompanied with the prayers of Angels, saints, priests, or just men, with us, as they fondly imagine and pretend; but with much more confidence in his grace, mercy, and merits, than if we prayed ourselves alone.

940: The Sacrifice is a Visible Propitiation for the Living and the Dead
SESSION XXII (Sept. 17, 1562) The Doctrine on the Most Holy Sacrifice of the Mass
And since in this divine sacrifice, which is celebrated in the Mass, that same Christ is contained and immolated in an unbloody manner, who on the altar of the Cross “once offered Himself” in a bloody manner [Heb. 9:27], the holy Synod teaches that this is truly propitiatory [can. 3], and has this effect, that if contrite and penitent we approach God with a sincere heart and right faith, with fear and reverence, “we obtain mercy and find grace in seasonable aid” [Heb. 4:16]. For, appeased by this oblation, the Lord, granting the grace and gift of penitence, pardons crimes and even great sins. For, it is one and the same Victim, the same one now offering by the ministry of the priests as He who then offered Himself on the Cross, the manner of offering alone being different. The fruits of that oblation (bloody, that is) are received most abundantly through this unbloody one; so far is the latter from being derogatory in any way to Him [can. 4]. Therefore, it is offered rightly according to the tradition of the apostles [can. 3], not only for the sins of the faithful living, for their punishments and other necessities, but also for the dead in Christ not yet fully purged.
