[Titus Quinctius Cincinnatus]

Were you aware that George Washington may have become a Catholic?

Then why did he request, and was granted, believer's baptism by John Gano, a Baptist pastor?

[Cronos]

Actually, Washington didn't -- it's called the "Alleged baptism of George Washington by Gano"

Rupert Hughes, Washington's biographer researched this and says that Gano was with Clinton's army in Valley Forge or the Potomac and there is no documentation of Gano ever being at Valley Forge, that there is nothing in Gano's own correspondence or his biography to suggest that the event took place, and that none of the 42 reputed witnesses ever documented the event

Washington attended services at numerous churches -- he was a great man and he was born Anglican, may have become Catholic, but that's an issue with him and God.
