Well, no. Moravians, the Unitas Fratrum, precede Luther by over a century. Followers of Jan Hus, the Hussites from whom the Moravians descended, are earlier still. Then, you have the Waldensians, earlier still.

It goes back even to the Bible. In part the Council of Jerusalem was called to put down the Judaizers. You had Adoptionism, Apollinarism, Arianism, Docetism.

The Councils of Nicaea and Constantinople were called to defend against these. The result was the Nicene Creed.

The Moravians were forcibly converted by the Habsburgs to Roman Catholicism from the Eastern Orthodox beliefs of their original conversion to Christianity. They sought a return to the orthodoxy of the two Eastern Orthodox missionaries, Cyril and Methodius, who converted their ancestors in the 9th Century, i.e. early Byzantine-inspired practices:
- liturgy in the language of the people (i.e. Czech)
- having lay people receive communion in both kinds (bread and wine - that is, in Latin, communio sub utraque specie)
- married priests
- elimination of unorthodox Roman novelties such as indulgences and the idea of Purgatory.
Show me the heresy in any of this using the Bible and you may have a point. You won't be able to do so, though.
