when was the trinity first mentioned in the bible
Trinity While scripture does not contain the word Trinity,[16] an indication of three distinct persons can be found in 1 John 5:7 for the validity of which exist a controversy known as Johannine Comma. Early Christian belief in the deity of Jesus Christ existed since the first century in the writings of John the Apostle. (John 1:1) Jesus is also quoted as attesting to being equal with the Father. (John 8:58, 10:30)
Holy, Holy, Holy "Holy, Holy, Holy!" is a Christian hymn written by Reginald Heber (1783–1826).[1][2][3] Its lyrics speak specifically of the Holy Trinity,[2][3] having been written for use on Trinity Sunday.[3] It quotes the Sanctus of the Latin Mass, which translated into English begins "Holy, Holy, Holy! Lord God of Hosts". The text also paraphrases Isaiah 6:3 and Revelation 4:1–11. John Bacchus Dykes composed the tune Nicaea for this hymn in 1861.[1][2][3] The tune name is a tribute to the First Council of Nicaea which formalized the doctrine of the Trinity in 325.[2][3]
