I believe you are either talking about the Leipzig debate or the Diet of Worms.
It was at the Diet of Worms were Luther had to defend his writings. This is were he made the “Here I stand” speech. However…
[quote:1mwwqma1]As to the doctrinal passages in his books, he (Luther,) agreed to retract any any that should be proved contrary to Scripture. To this Eck, in Latin, made an objection that well expressed the view of the Church:
‘Martin, your plea to be heard form Scripture is the one always made by heretics. You do nothing but renew the errors of Wyclif and Huss…How can you assume that you are the only one to understand the sense of Scripture? Would you put your judgement above that of so many famous men and claim that you know more than all of them? You have no right to call into question the most holy orthodox faith, instituted by Christ the perfect Lawgiver, proclaimed throughout the world by the Apostles, sealed by the red blood of the martyrs, confirmed by the sacred councils, and defined by the Church…and which we are forbidden by the Pope and the Emperor to discuss, lest there be no end to debate. I ask you, Martin-answer candidly and without distinctions-do you or do you not repudiate your books and the errors which they contain?

Then in German, Luther replied,
[quote:1mwwqma1]’Unless I am convicted by scripture and plain reason-I do not accept the authority of Popes and councils, for they have contradicted each other- my conscience is captive to the word of God. I cannot and will not recant anything, for to go against conscience is neither right nor safe. God help me. Amen.’
The earliest printed version added the words: “Here I stand, I cannot do otherwise.” The words, though not recorded on the spot, my nevertheless be genuine, because the listeners at the moment may have have been too moved to write.

As for the Leipzig debate,
[quote:1mwwqma1]As might be expected, the debate revealed that Eck was more of an authority in Scholastic theology and on the period of the Reformed Councils than was Luther, but he was no match for Luther in the early history of the Christian Church either in his familiarity with the sources or in their critical evaluation.

In my opinion, since both men are well educated and excel in some subjects but may struggle in others is quite unfair to say who is the the true victor of the debates.
