What was Howard Hughes's religion?

Howard Hughes was born in 1905 and baptismal records in an Episcopalian church in his home state of Iowa show he was baptised into that religion. Towards the end of his life, Hughes was heavily influenced by The Church Of Jesus Christ Of Latterday Saints (the Mormon Church) who surrounded him because he claimed they were the only people he could trust, although he never became a Mormon himself. Upon Hughes's death in 1976, The Mormon Church produced a will in which Hughes had donated approximately 1.5 billion dollars to various charities. Hughes's relatives contested the will produced by the The Mormon Church. The American courts rejected that particular will two years later. He was declared intestate and his wealth was eventually divided amongst his family.
