Please please please help me with this answer. Going to have discussion with nondenominational friend soon but would like your response.
So Heb 8:13 talks about the first covenant is obsolete and now we are under the new covenant. But my friend states that the things that Catholics do and most protestants … like tithing (especially tithing), or incense, or the priesthood, etc, that is prescribed in the old law… if a church does any of that , then they are practicing old covenant/old law which goes against Hebrews and is practicing two covenants. Of course, I know we don’t sacrifice animals etc like they did in the old law, its now the one, true sacrifice of Christ, but he states that if you practice anything (ie. tithing), then you should practice all laws. … which of course, is not biblical. Thus, Catholics practice two covenants.
I asked him what about Matthew 5:17, but he said Christ was just instructing the Jews, which do practice old law.
which brings up another good Q: does Matthew 5:17 contradict Hebrews 8?
I look forward to your response, thanks in advance

The idea that Jesus was speaking to Jews only in Matt 5 is pure contrived nonsense for the purpose of supporting a false gospel. The difference between the Old Covenant and the New is that, in the Old, we’re to obey God’s Law in order to prove our righteousness, as if we possessed or could attain that righteousness on our own, by our own efforts. The real purpose in this, from God’s perspective, was to demonstrate just how
impossible that is for man, because man’s not capable of righteousness without grace, without
God, IOW, apart from Whom he can do nothing, but
with Whom all things are possible.
The New Covenant brings about authentic righteousness as it brings about reconciliation with and therefore communion with God, because from that vantage point He may do His work In us. Read the New Covenant prophecies in Jer 31:33-34, which are also quoted in Hebrews 8 & 10. This shows God’s purpose: we’re still to obey, but
He’s to be our righteousness, the cause of our obedience, as was always meant to be. This was the relationship which Adam shattered in Eden.
What Jesus accomplished was reestablishment of communion with God first of all: we don’t approach God by first becoming righteous, rather we become righteous by first approaching God. We don’t obey the Law in order to unite with God, rather we must first unite with God in order to obey the Law.
"For it is not those who hear the law who are righteous in God’s sight, but it is those who obey the law who will be declared righteous." Rom 2:13
From the Catechism:
**1965 The New Law or the Law of the Gospel is the perfection here on earth of the divine law, natural and revealed. It is the work of Christ and is expressed particularly in the Sermon on the Mount. It is also the work of the Holy Spirit and through him it becomes the interior law of charity: "I will establish a New Covenant with the house of Israel. . . . I will put my laws into their hands, and write them on their hearts, and I will be their God, and they shall be my people."19
1966 The New Law is the grace of the Holy Spirit given to the faithful through faith in Christ. It works through charity; it uses the Sermon on the Mount to teach us what must be done and makes use of the sacraments to give us the grace to do it:
If anyone should meditate with devotion and perspicacity on the sermon our Lord gave on the mount, as we read in the Gospel of Saint Matthew, he will doubtless find there . . . the perfect way of the Christian life. . . . This sermon contains . . . all the precepts needed to shape one’s life.20
1967 The Law of the Gospel “fulfills,” refines, surpasses, and leads the Old Law to its perfection.21 In the Beatitudes, the New Law fulfills the divine promises by elevating and orienting them toward the “kingdom of heaven.” It is addressed to those open to accepting this new hope with faith - the poor, the humble, the afflicted, the pure of heart, those persecuted on account of Christ and so marks out the surprising ways of the Kingdom.
1968 The Law of the Gospel fulfills the commandments of the Law. The Lord’s Sermon on the Mount, far from abolishing or devaluing the moral prescriptions of the Old Law, releases their hidden potential and has new demands arise from them: it reveals their entire divine and human truth. It does not add new external precepts, but proceeds to reform the heart, the root of human acts, where man chooses between the pure and the impure,22 where faith, hope, and charity are formed and with them the other virtues. The Gospel thus brings the Law to its fullness through imitation of the perfection of the heavenly Father, through forgiveness of enemies and prayer for persecutors, in emulation of the divine generosity.23**
