EWTN Catholic Q&A
George Washington
Question from Fabiana on 09-07-2001:

Is it true that George Washington was baptized Catholic on his deathbed? Is it also true that he received an apparition of the Virgin Mary and saw the entire history of the United States and the three great CHASTISEMENTS that would come to the Republic? (I read that his vision of Blessed Virgin and the future of the US is recorded at the Library of Congress)

Answer by Dr. William Carroll on 09-07-2001:

Unfortunately there is no historically reliable proof of this. The Library of Congress has the greatest collection in the world, which includes almost everything. It is no proof at all that documents mentioning this are filed there. - Dr. Carroll
