Because you can't read?

I will ask the Father, and he shall give you another Paraclete, that he may abide with you for ever

[...]

the Paraclete, the Holy Ghost, whom the Father will send in my name, he will teach you all things, and bring all things to your mind, whatsoever I shall have said to you

(John 14)

hold the traditions which you have learned, whether by word, or by our epistle (2 Thessalonians 2:14)

That's a ridiculous argument. Those verses don't give anyone license to make things up and teach them as fact because their tradition says that their tradition on equal footing with Scripture.

Word of mouth over hundreds or thousands of years WILL be corrupted and is unreliable.

Of course. I agree. Tell it to the Protestant charlatans.

Word of mouth over hundreds or thousands of years WILL be corrupted

This is why the Church carefully preserves the Holy Tradition. We know with precision what is in it and what is not.
