From this article.
We accept Sri Krsna as the Supreme Personality of Godhead, but the father of Jesus Christ, God, Allah, Khoda, and Jehovah are also said to be the Supreme Personality of Godhead. There are not two Gods. The fact is that the Supreme Lord is one without a second. In different languages, in different countries, and in different sections of the world, people call that same Supreme Lord by various names.
Steven Rosen includes Vishnu and Rama as other equivalent names.
Is this the mainstream Gaudiya view?
