Yes, they did!

Luther:
No, they didn't.

Yes, they did.

Idiocy...there was no Tradition or Magesterium.

Yes, there was. 

Magisterium simply means an authoritative teacher. In this case, the Church represented by Sts. Paul and Silas.

And Tradition, St. Paul confirms that he taught the Thessalonians Tradition:

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.

Sincerely,

De Maria
