Can you show us where Paul divided the Old Covenant into "the moral law", and "the ceremonial law"?
Yes.
Ceremonial: Shadows that pointed to Christ and were only in place until the coming of Christ, the one who fulfilled them.
Christians are now free to not to partake in dietary restrictions, temple worship, animal sacrifices, cleansing, feasts, sabbaths, because Christ fulfilled these terms of the old covenant, eternally sanctifying us
Hebrews 9:8-10 By this arrangement the Holy Spirit was showing that the way into the Most Holy Place had not yet been disclosed as long as the first tabernacle was still standing. It is an illustration for the present time, because the gifts and sacrifices being offered were unable to cleanse the conscience of the worshiper. They consist only in food and drink and special washings—external regulations imposed until the time of reform.
Hebrews 10:1 For the law is only a shadow of the good things to come, not the realities themselves. It can never, by the same sacrifices offered year after year, make perfect those who draw near to worship. If it could, would not the offerings have ceased? For the worshipers would have been cleansed once for all, and would no longer have felt the guilt of their sins
Colossians 2:16-17 Therefore let no one judge you by what you eat or drink, or with regard to a feast, a New Moon, or a Sabbath. These are a shadow of the things to come, but the body that casts it belongs to Christ.

Moral: God's eternal righteous standard: Love God and your Neighbor, binding for all of His people for all time. Not for salvation but for justification of our faith.
Christ fulfilled God's eternal moral standard, but Christians are not now free to lie, cheat, steal, covet, partake in idolatry.
Romans 13:8-10 Be indebted to no one, except to one another in love. For he who loves his neighbor has fulfilled the law. The commandments “Do not commit adultery,” “Do not murder,” “Do not steal,” “Do not covet,”
a and any other commandments, are summed up in this one decree: “Love your neighbor as yourself.”
b Love does no wrong to its neighbor. Therefore love is the fulfillment of the law.
Galatians 5:13-15 For you, brothers, were called to freedom; but do not use your freedom as an opportunity for the flesh. Rather, serve one another in love. The entire law is fulfilled in a single decree: “Love your neighbor as yourself.”
James 2:16-17 If one of you tells him, “Go in peace; stay warm and well fed,” but does not provide for his physical needs, what good is that? So too, faith by itself, if it does not result in action,
f is dead.
Romans 6:1-2 What then shall we say? Shall we continue in sin so that grace may increase?
2Certainly not! How can we who died to sin live in it any longer?
Galatians 5:19-20 The acts of the flesh are obvious: sexual immorality, impurity, and debauchery; idolatry and sorcery; hatred, discord, jealousy, and rage; rivalries, divisions, factions, and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who practice such things will not inherit the kingdom of God.
What do we find below?
What are the two covenants Paul is speaking about?
Paul is talking about 2 covenants: the old covenant and the new covenant.
I think this is where it is important to understand what a covenant is.
1242
diathḗkē (from
1223 /diá, "thoroughly," intensifying
5087 /títhēmi, "place, set") – properly, a set-agreement having
complete terms determined by the
initiating party, which also are fully affirmed by the one entering
the agreement.
A covenant is an agreement between the party initiating the covenant, and the party entering into the agreement.
The old covenant was an AGREEMENT between God, the one initiating the covenant, and the nation of Israel, the one entering into the agreement. If Israel obeyed all of the laws of moses: moral, civil, ceremonial, they would be blessed in the land of Israel (deuteronomy 28:1-14). If Israel did not follow all of the laws of moses: moral, civil, ceremonial, then Israel would be cursed (deuteronomy 28:15-68). This is the old covenant.
The old covenant/AGREEMENT is what is done away with for the people of God, after its shadows were brought to completion in Christ. The AGREEMENT for Israel to obey/disobey all of the laws for earthl blessings/curses was made obsolete at the cross, and its visible carcass or "desolate house" vanished away 40 years after.
Hebrews 8:13 By speaking of a new covenant, He has made the first one obsolete; and what is obsolete and aging will soon disappear.
The term "the moral law" is found in the Westminster Confession of Faith, but it is not found in the Bible.
This is not a sufficient argument, however. The term "Holy Trinity" is found in the westminster confession of faith, but not in the Bible. Therefore, we should not hold to the doctrine of the trinity, as it is not found in scripture? No of course not.
It is the same plan as he has for all peoples - that they be grafted into the vine. He is a diagram explaining 'expansion theology.'
