Jesus and the 13/14 Apostles all taught LOADS of DOGMAS that the Holy Spirit chose to keep out of the Church.

Lutero:

The Catholic perspective.....

Jesus and the 13/14 Apostles all taught LOADS of DOGMAS that (for reasons never explained) the Holy Spirit chose to keep out of His Scriptures to the Church.

Lets compare your dogmas to Scripture and our doctrines to Scripture. 

NONETHELESS (in a process never explained).... perhaps many centuries later..... somehow (how is never explained) the RC Denomination found out about it.... and eventually (for reasons never explained) did what the Holy Spirit chose not to do - disclose it. BTW, this is a fundamental LDS concept, too. Follow?

The Catholic Church is described in Scripture. First, Jesus Christ appointed a Pastor as head of the entire Church: 
John 21:17 
He saith unto him the third time, Simon, son of Jonas, lovest thou me? Peter was grieved because he said unto him the third time, Lovest thou me? And he said unto him, Lord, thou knowest all things; thou knowest that I love thee. Jesus saith unto him, Feed my sheep. 

I see only a few Churches with such a Pastor. Further, Jesus Christ said that the Pastor over His Church would be infallible: 

Matthew 16:17-19 (King James Version) 
17And Jesus answered and said unto him, Blessed art thou, Simon Barjona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven.18And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it. 19And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven. 

The list of Churches accept this teaching gets smaller. Certainly, all Protestant denominations can now be eliminated. 

Jesus Christ not only said that the Pastor was infallible but Scripture describes the Church as infallible: 
Ephesians 3:10 
To the intent that now unto the principalities and powers in heavenly places might be known by the church the manifold wisdom of God, 

The list remains the same, but now I can certainly eliminate all Protestant denominations. 

Back to Matt 16:18, Scripture says that Jesus Christ established one Church. History shows that all the Churches sprang from the Church which is frequently described as the Mother Church. The Catholic Church. 

By simple logic of elimination, that leaves only the Catholic Church.

Of course, all this is theoretically possible, but every Catholic known to me freely admits that there is NOTHING, nothing at all, absolutely ZERO, to suggest that it's true.

You mean every ex-catholic who left the Catholic Church because they didn't understand their faith.

It's a claim - entirely unsubstantiated but of course theoretically possible (since Scripture says ALL THINGS are possible with God).

It is not only possible, it is true. Whereas we can easily eliminate EVERY Protestant Church from Scripture:

Scripture alone? Scripture says:
2 Thessalonians 2:15

King James Version (KJV)
¹⁵ Therefore, brethren, stand fast, and hold the traditions which ye have been taught, whether by word, or our epistle.

Faith alone? Scripture says:
James 2:24

King James Version (KJV)²⁴ Ye see then how that by works a man is justified, and not by faith only.

Is there any Protestant doctrine which doesn't believe those two heresies?

BTW, the OOC and EOC both have the same "tradition" it just isn't at all the same; SOMEONE is "remembering" this Tradition wrong, obviously. But since none of them will share what this "tradition" is (they keep it a secret phantom), no one has any way of knowing whether anyone is right about what this "tradition" says - these teachings the Holy Spirit chose to not include in His Scriptures to the church. The RCC says that Tradition says the Pope is Infallible, the EOC says it does not - but neither will show us this "Tradition" so we can see who is right. The RCC says that Tradition teaches Purgatory, but the EOC says it doesn't but neither will show us this Tradition so we can see who is right. It's a phantom. Each claiming it "has" it, referring to it often, but never revealing what "it" is, only what IT exclusively says it says (but disagreeing with the others who "see" it but won't share it).

Protestant doctrines contradict Scripture. 

EOC's, at least, have the Sacraments. And because of them, they are saved in this life. 

When we approach the Sacraments, we approach Jesus Christ in the proper disposition of faith, believing that He can do what He promised.

But only those who have first, proven their faith by their works, will receive the mercy of God in the Sacraments. This is done by first studying to show ourselves approved (RCIA). These are they who are justified because they are “doers of the law” (Rom 2:13).

Say for instance that you are a doer of the law, but you are not Catholic or Orthodox. Will you be justified by God? God is your judge. But if you are truly a doer of the law, you will be justified, ON THE LAST DAY. (Rev 20)

Now, say that you are a doer of the law, but you are Catholic or Orthodox. Will you be justified by God? Again, God is judge. But if you are truly a doer of the law, you will be justified, in the Sacraments.

That is not a guarantee of salvation for those who attend the Sacraments. Remember Scripture says:
1 Peter 4:17?For the time is come that judgment must begin at the house of God: and if it first begin at us, what shall the end be of them that obey not the gospel of God?

And also:
Mark 16:16
King James Version (KJV)
16 He that believeth and is baptized shall be saved; but he that believeth not shall be damned.

One must approach the Font of Grace in the proper disposition of faith.

For example, a Catholic will insist, "The DOGMA of the Assumption of Mary was first alluded to, well, sort of, as early as the FIFTH CENTURY!!!!!"

That's a lot earlier than any Protestant doctrine. 

This, somehow, proves that Jesus and all 13/14 Apostles taught it, as Dogma, before 31 AD, but somehow no one seems to have known about it until maybe as early as the Fifth Century when, somehow, sort of, the RC Denomination began to teach it - sort of, and in the maybe 1500 years later decided to tell the world that it's a dogmatic fact. Okay.... but how this all reveals that Jesus and the 13/14 Apostles taught it was always a point of some mystery to me during my Catholic days. BTW, the EOC says there is NOTHING of the sort in Tradition. Who knows? Neither denomination will tell us the content of this mysterious "Tradition."

Read the Scriptures. Rev 12:1 shows Mary in heaven. And the book of Revelations was written by the Apostle John.

Sincerely,

De Maria
