It is not known what the punishment will be for Gray's comments, which were made in 2012.
It is possible that the player may face a ban and/or a fine in relation to such comments.
One of the tweets he posted said: "Is it me or are there gays everywhere? #Burn #Die #Makesmesick".
However, Gray did apologise following the circulation of his previous posts on social media and claimed that he was now a "different person".
An FA statement read: "Burnley’s Andre Gray has been charged with misconduct in respect of social media comments made between 9 January 2012 and 11 March 2012. It is alleged the comments were abusive and/or insulting and/or improper and/or brought the game into disrepute contrary to FA Rule E3(1). It is further alleged that these breaches include reference to an "aggravating factor", namely, sexual orientation and/or gender and/or colour and/or race contrary to FA Rule E3(2)".
