Margaret McDonald

Margaret McDonald was born in 1815and lived in Port Glasgow, Scotland during the beginning years of the Dispensationalist movement under John Nelson Darby. McDonald was fifteen years old in 1830 when she claimed to be a prophetess. She then not long after her revelation wrote down her account of everything and sent hand-written copies of it to a number of Christian leaders. Her writings were considered to be worng and was blamed for inventing the pre-tribulation rapture of the Church. Others said that she was amongst the company of false prophets who were causing disturbances in Edward Irving's church at the time. Some people wrote that Margaret and other so called prophets and visionaries spoke under the direction of a demonic power. She is very similar to Nostradamus.
