Sri Ramakrishna did.
"God can be realized through all paths. All religions are true. The important thing is to reach the roof. You can reach it by stone stairs or by wooden stairs or by bamboo steps or by a rope. You can also climb up by a bamboo pole." ~ Ramakrishna
Also I did.
My definition does not necessarily declare theistic belief. Yes, gods exists for many, yet for others they do not exist, and yet others are uncertain if they exist. So it could declare atheistic or agnostic belief (or lack thereof).
