Here is the difference (hopefully to get back on the SDA topic):
I do not believe Catholic doctrine to be Christian because of how far it has gone over the centuries.
"As a church, the Catholic Church came into existence in the 4th century encompassing Christians within the Roman Empire."
Your forgetting the other Catholics who got nothing to do with Roman Empire, Like the Eastern Orthodox Catholics. How you going to explain them away, when they also can trace themselves to Jesus Christ and still recognize Roman side catholics as Catholics?
"Prior to the Roman Catholic Church we had Cloement of Rome, Ignatius, Polycarp (a disciple of John), Justin Martyr, Irenaeus, Clement of Alexandria, Origen, and perhaps I can squeeze John Chrysostom in there (I can't remember his dates, but it is around 400 AD)."

Ignatius of Antioch
"Consider how contrary to the mind of God are the heterodox in regard to the grace of God which has come to us. They have no regard for charity, none for the widow, the orphan, the oppressed, none for the man in prison, the hungry or the thirsty. They abstain from the Eucharist and from prayer, because they do not admit that the Eucharist is the flesh of our Savior Jesus Christ, the flesh which suffered for our sins and which the Father, in His graciousness, raised from the dead."
"Letter to the Smyrnaeans", paragraph 6. circa 80-110 A.D.
"Come together in common, one and all without exception in charity, in one faith and in one Jesus Christ, who is of the race of David according to the flesh, the son of man, and the Son of God, so that with undivided mind you may obey the bishop and the priests, and break one Bread which is the medicine of immortality and the antidote against death, enabling us to live forever in Jesus Christ."
-"Letter to the Ephesians", paragraph 20, c. 80-110 A.D.
"I have no taste for the food that perishes nor for the pleasures of this life. I want the Bread of God which is the Flesh of Christ, who was the seed of David; and for drink I desire His Blood which is love that cannot be destroyed."
-"Letter to the Romans", paragraph 7, circa 80-110 A.D.
"Take care, then who belong to God and to Jesus Christ - they are with the bishop. And those who repent and come to the unity of the Church - they too shall be of God, and will be living according to Jesus Christ. Do not err, my brethren: if anyone follow a schismatic, he will not inherit the Kingdom of God. If any man walk about with strange doctrine, he cannot lie down with the passion. Take care, then, to use one Eucharist, so that whatever you do, you do according to God: for there is one Flesh of our Lord Jesus Christ, and one cup in the union of His Blood; one altar, as there is one bishop with the presbytery and my fellow servants, the deacons."
-Epistle to the Philadelphians, 3:2-4:1, 110 A.D.
Justine Martyr:
"This food we call the Eucharist, of which no one is allowed to partake except one who believes that the things we teach are true, and has received the washing for forgiveness of sins and for rebirth, and who lives as Christ handed down to us. For we do not receive these things as common bread or common drink; but as Jesus Christ our Savior being incarnate by God's Word took flesh and blood for our salvation, so also we have been taught that the food consecrated by the Word of prayer which comes from him, from which our flesh and blood are nourished by transformation, is the flesh and blood of that incarnate Jesus."
"First Apology", Ch. 66, inter A.D. 148-155.
"God has therefore announced in advance that all the sacrifices offered in His name, which Jesus Christ offered, that is, in the Eucharist of the Bread and of the Chalice, which are offered by us Christians in every part of the world, are pleasing to Him."
"Dialogue with Trypho", Ch. 117, circa 130-160 A.D.
Moreover, as I said before, concerning the sacrifices which you at that time offered, God speaks through Malachias, one of the twelve, as follows: 'I have no pleasure in you, says the Lord; and I will not accept your sacrifices from your hands; for from the rising of the sun until its setting, my name has been glorified among the gentiles; and in every place incense is offered to my name, and a clean offering: for great is my name among the gentiles, says the Lord; but you profane it.' It is of the sacrifices offered to Him in every place by us, the gentiles, that is, of the Bread of the Eucharist and likewise of the cup of the Eucharist, that He speaks at that time; and He says that we glorify His name, while you profane it."
-"Dialogue with Trypho", [41: 8-10]
ST. JOHN Chrysostom
"When the word says, 'This is My Body,' be convinced of it and believe it, and look at it with the eyes of the mind. For Christ did not give us something tangible, but even in His tangible things all is intellectual. So too with Baptism: the gift is bestowed through what is a tangible thing, water; but what is accomplished is intellectually perceived: the birth and the renewal. If you were incorporeal He would have given you those incorporeal gifts naked; but since the soul is intertwined with the body, He hands over to you in tangible things that which is perceived intellectually. How many now say, 'I wish I could see His shape, His appearance, His garments, His sandals.' Only look! You see Him! You touch Him! You eat Him!"
-"Homilies on the Gospel of Matthew" [82,4] 370 A.D.
"I wish to add something that is plainly awe-inspiring, but do not be astonished or upset. This Sacrifice, no matter who offers it, be it Peter or Paul, is always the same as that which Christ gave His disciples and which priests now offer: The offering of today is in no way inferior to that which Christ offered, because it is not men who sanctify the offering of today; it is the same Christ who sanctified His own. For just as the words which God spoke are the very same as those which the priest now speaks, so too the oblation is the very same."
Source: St. John Chrysostom, "Homilies on the Second Epistle to Timothy," 2,4, c. 397 A.D.
"It is not the power of man which makes what is put before us the Body and Blood of Christ, but the power of Christ Himself who was crucified for us. The priest standing there in the place of Christ says these words but their power and grace are from God. 'This is My Body,' he says, and these words transform what lies before him."
Source: St. John Chrysostom, "Homilies on the Treachery of Judas" 1,6; d. 407 A.D.:
"'The cup of blessing which we bless, is it not communion of the Blood of Christ?' Very trustworthily and awesomely does he say it. For what he is saying is this: 'What is in the cup is that which flowed from His side, and we partake of it.' He called it a cup of blessing because when we hold it in our hands that is how we praise Him in song, wondering and astonished at His indescribable Gift, blessing Him because of His having poured out this very Gift so that we might not remain in error, and not only for His having poured out It out, but also for His sharing It with all of us."
-"Homilies on the First Letter to the Corinthians" [24,1] ca. 392 A.D.
ST. Clement of Alexandria:
"The Blood of the Lord, indeed, is twofold. There is His corporeal Blood, by which we are redeemed from corruption; and His spiritual Blood, that with which we are anointed. That is to say, to drink the Blood of Jesus is to share in His immortality. The strength of the Word is the Spirit just as the blood is the strength of the body. Similarly, as wine is blended with water, so is the Spirit with man. The one, the Watered Wine, nourishes in faith, while the other, the Spirit, leads us on to immortality. The union of both, however, - of the drink and of the Word, - is called the Eucharist, a praiseworthy and excellent gift. Those who partake of it in faith are sanctified in body and in soul. By the will of the Father, the divine mixture, man, is mystically united to the Spirit and to the Word.",
-"The Instructor of the Children". [2,2,19,4] ante 202 A.D.,
"The Word is everything to a child: both Father and Mother, both Instructor and Nurse. 'Eat My Flesh,' He says, 'and drink My Blood.' The Lord supplies us with these intimate nutrients. He delivers over His Flesh, and pours out His Blood; and nothing is lacking for the growth of His children. O incredible mystery!",
-"The Instructor of the Children" [1,6,41,3] ante 202 A.D.. ,
Am I not better off thinking all the early church fathers are heretics because they all insist in believing in the Real Presence of the Eucharist as Catholics do?
What if next I pull pages of them saying good works are necessary?
How can you say we are less legit then they are? when they are still teaching exactly the the things we believe?
