in 1864, an anonymous pamphlet was published in manila, criticizing the prejudice in the church, and providing rebuttals against several canards against the native clergy. although the document was unsigned, historians believe the author to be burgos, based on its style and content. burgos also penned several signed articles later in his life, in response to a series of anonymous written attacks on the filipino clergy. though burgos offered few new ideas, his name caught the attention of spanish authorities, who would report that the native clergy was becoming separatist.
