[This post will likely be added to a general post on inclusivism and therefore disappear from the homepage section.]
William Booth, the founder of the Salvation Army, was an inclusivist.
The following are his words:
“Millions have entered the gates that lead to the Celestial City with the sentiment in their hearts which we Salvationists express by our song, “His Blood can make the foulest clean.” Millions upon millions more will reach the Golden Pavement who have never heard His precious name before they gained the Heavenly Shores. Sincere souls who by living up to the light they possess, prove that if they had had the opportunity they would have laid themselves at the Savior’s feet, will not have to suffer banishment on account of their ignorance. You will remember Paul  says, “in every nation he that feareth Him, and worketh righteousness, is accepted with Him” (Acts 10:35). This shows that God is going to deal with people according to their sincerity. If they are obedient to what they hear, there will be Salvation for them; and if they have never heard but would have been obedient if they had heard, they will not be rejected.”

 It was noted by Wayne Scott that William Booth mistakingly attributed these words to Paul. Peter was actually speaking.
