I see someone was studying the weekly Torah portion, and some say Catholics do not know the scriptures ...
I find the story of Korah a profound example of apostolic succession and Protestantism pre-figured. Now Korah, the son of Izhar, the son of Kohath, the son of Levi, and Dathan and Abiram, the sons of Eliab, and On, the son of Peleth, sons of Reuben, took men: And they rose up before Moses, with certain of the children of Israel, two hundred and fifty princes of the assembly, famous in the congregation, men of renown: And they gathered themselves together against Moses and against Aaron, and said unto them, Ye take too much upon you, seeing all the congregation are holy, every one of them, and the Lord is among them: wherefore then lift ye up yourselves above the congregation of the Lord? And when Moses heard it, he fell upon his face: And he spake unto Korah and unto all his company, saying, Even to morrow the Lord will shew who are his, and who is holy; and will cause him to come near unto him: even him whom he hath chosen will he cause to come near unto him. This do; Take you censers, Korah, and all his company; And put fire therein, and put incense in them before the Lord to morrow: and it shall be that the man whom the Lord doth choose, he shall be holy: ye take too much upon you, ye sons of Levi. And Moses said unto Korah, Hear, I pray you, ye sons of Levi: Seemeth it but a small thing unto you, that the God of Israel hath separated you from the congregation of Israel, to bring you near to himself to do the service of the tabernacle of the Lord, and to stand before the congregation to minister unto them? And he hath brought thee near to him, and all thy brethren the sons of Levi with thee: and seek ye the priesthood also? For which cause both thou and all thy company are gathered together against the Lord: and what is Aaron, that ye murmur against him? And Moses sent to call Dathan and Abiram, the sons of Eliab: which said, We will not come up: Is it a small thing that thou hast brought us up out of a land that floweth with milk and honey, to kill us in the wilderness, except thou make thyself altogether a prince over us? Moreover thou hast not brought us into a land that floweth with milk and honey, or given us inheritance of fields and vineyards: wilt thou put out the eyes of these men? we will not come up. And Moses was very wroth, and said unto the Lord, Respect not thou their offering: I have not taken one ass from them, neither have I hurt one of them. And Moses said unto Korah, Be thou and all thy company before the Lord, thou, and they, and Aaron, to morrow: And take every man his censer, and put incense in them, and bring ye before the Lord every man his censer, two hundred and fifty censers; thou also, and Aaron, each of you his censer. And they took every man his censer, and put fire in them, and laid incense thereon, and stood in the door of the tabernacle of the congregation with Moses and Aaron. And Korah gathered all the congregation against them unto the door of the tabernacle of the congregation: and the glory of the Lord appeared unto all the congregation. And the Lord spake unto Moses and unto Aaron, saying, Separate yourselves from among this congregation, that I may consume them in a moment. And they fell upon their faces, and said, O God, the God of the spirits of all flesh, shall one man sin, and wilt thou be wroth with all the congregation? And the Lord spake unto Moses, saying, Speak unto the congregation, saying, Get you up from about the tabernacle of Korah, Dathan, and Abiram. And Moses rose up and went unto Dathan and Abiram; and the elders of Israel followed him. And he spake unto the congregation, saying, Depart, I pray you, from the tents of these wicked men, and touch nothing of their's, lest ye be consumed in all their sins. So they gat up from the tabernacle of Korah, Dathan, and Abiram, on every side: and Dathan and Abiram came out, and stood in the door of their tents, and their wives, and their sons, and their little children. And Moses said, Hereby ye shall know that the Lord hath sent me to do all these works; for I have not done them of mine own mind. If these men die the common death of all men, or if they be visited after the visitation of all men; then the Lord hath not sent me. But if the Lord make a new thing, and the earth open her mouth, and swallow them up, with all that appertain unto them, and they go down quick into the pit; then ye shall understand that these men have provoked the Lord. And it came to pass, as he had made an end of speaking all these words, that the ground clave asunder that was under them: And the earth opened her mouth, and swallowed them up, and their houses, and all the men that appertained unto Korah, and all their goods. They, and all that appertained to them, went down alive into the pit, and the earth closed upon them: and they perished from among the congregation. And all Israel that were round about them fled at the cry of them: for they said, Lest the earth swallow us up also. And there came out a fire from the Lord, and consumed the two hundred and fifty men that offered incense. And the Lord spake unto Moses, saying, Speak unto Eleazar the son of Aaron the priest, that he take up the censers out of the burning, and scatter thou the fire yonder; for they are hallowed. The censers of these sinners against their own souls, let them make them broad plates for a covering of the altar: for they offered them before the Lord, therefore they are hallowed: and they shall be a sign unto the children of Israel. And Eleazar the priest took the brasen censers, wherewith they that were burnt had offered; and they were made broad plates for a covering of the altar: To be a memorial unto the children of Israel, that no stranger, which is not of the seed of Aaron, come near to offer incense before the Lord; that he be not as Korah, and as his company: as the Lord said to him by the hand of Moses. But on the morrow all the congregation of the children of Israel murmured against Moses and against Aaron, saying, Ye have killed the people of the Lord. And it came to pass, when the congregation was gathered against Moses and against Aaron, that they looked toward the tabernacle of the congregation: and, behold, the cloud covered it, and the glory of the Lord appeared. And Moses and Aaron came before the tabernacle of the congregation. And the Lord spake unto Moses, saying, Get you up from among this congregation, that I may consume them as in a moment. And they fell upon their faces. And Moses said unto Aaron, Take a censer, and put fire therein from off the altar, and put on incense, and go quickly unto the congregation, and make an atonement for them: for there is wrath gone out from the Lord; the plague is begun. And Aaron took as Moses commanded, and ran into the midst of the congregation; and, behold, the plague was begun among the people: and he put on incense, and made an atonement for the people. And he stood between the dead and the living; and the plague was stayed. Now they that died in the plague were fourteen thousand and seven hundred, beside them that died about the matter of Korah. And Aaron returned unto Moses unto the door of the tabernacle of the congregation: and the plague was stayed.

Orthodox folks just say the bread and wine change when consecrated without further explaining the point. For them, you either accept what Christ Himself said or you have no faith in Christ. For Orthodox folks, someone saying they have faith in Christ while denying what Christ Himself said is foolishness at best and a willful denial that Christ as God at worst.
The Catholic Church elaborated what changes with consecration using the difference between substance and accident, terminology commonly used in philosophy, theology, and science discussions during the Middle Ages and well understood. Basically, it's a way to describe the nature of something independent of the physical properties it has.
The nature of something can change without there being any perceptible change to the physical attributes it has which is exactly what the Catholic Church teaches and always has taught. The Catholic Church has never taught that the accidents of the consecrated bread and wine change, but they have always taught that the substance changes into the body and blood of Christ exactly as Christ Himself said it does.
Neither approach to undersanding what Christ says takes place matters to Protestant folks. That's because in reality as opposed to their espoused doctrine, the overwhelming majority of Protestant folks place their faith in Self first and science when it serves their purposes, not in Jesus Christ.
They pretend to accept that Christ is God incarnate but then refuse to accept what Christ Himself said. They even routinely insist that if Christ meant exactly what He said then science could prove that the bread and wine are changed.
So much for "Faith Alone" as taught by those who so obviously have none.
The argument about the Real Presence is primarily just a way of denying the need for a sacrificial priesthood exactly the same way Korah denied the need for such a priesthood. The Lutheran (as well as a very few other small segments of various groups) approach is to not deny what Christ Himself said, but to claim that it is individual faith that consecrates the bread and wine, not consecreation by the priest in spite of Christ's actions at the Last Supper. That is, they deny what Christ did but not what Christ said.
The majority of Protestantism doesn't stop there, they deny both what Christ said and what Christ did at the Last Supper. They simply ignore the fact that what Jesus Christ, God incarnate, both said and did at the Last Supper were forshadowed in the Old Testament.
The vast majority of Protestant folks ignore it all, in spite of their claim to base what they believe on Scripture Alone they throw out anything in Scripture that complicates their embrace of the heresy of Korah. They ignore the Old Testament being fulfilled and claim the Last Supper is essentially meaningless because Christ and the Apostles were just having a snack. A grape Popsicle and handful of Cheerios for all intents and purposes.
So much for "Scripture Alone" as taught by those who so obviously ignore Scripture.
