Address those conundrums of YOUR Protestant faith

Luther: 

The Bible is clear that we can't be saved by keeping the law...we can't keep it.

Please provide the quote. Because if you do, you will have Scripture contradicting itself. Scripture says:
Luke 1:6

King James Version (KJV)
⁶ And they were both righteous before God, walking in all the commandments and ordinances of the Lord blameless.

Paul does not teach law keeping salvation.

Apparently he teaches law keeping justification however.

Romans 2:13
King James Version (KJV)¹³ (For not the hearers of the law are just before God, but the doers of the law shall be justified.

James does not teach it either, neither do they teaching justification before God by works.

They teach it by FAITH AND WORKS.

You Catholics speak out of both sides of your mouths. You tell us you don't teach a works based gospel and then your turn around and proceed to do just that.

On the contrary, we preach salvation by faith AND WORKS in accordance with the teaching of Scripture. Whereas, you claim that you believe in Scripture alone, but 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.

Now, compare your teaching to Scripture.
You claim, "justification by faith alone".
Scripture says, "Not by faith only".

Please, twist your way around that one.

Now here's another. You claim St. Paul teaches justification by faith alone.
But St. Paul says: Doers of the law are justified.

Please address those conundrums of YOUR faith.

Sincerely,

De Maria
