Are there any basic differences between the following: baptists, free-will baptists, regular baptists, first?

there is no difference because the meaning of the word baptist is the person who baptize another. like St John, the Baptists, he was a baptist. during his days and the person who baptized Jesus Christ. The pastor on the baptist Church was lost to follow the old true path to heaven and he is still wanting to have companions to be lost. He could not understand the word baptist. To be sure of it, see your encyclopedia or dictionary
