Tetragrammaton St Peter's Basilica Vatican City Italy; It is barely visible in gold, but note the trinitarian symbol, the triad. The trinity is not a Bible teaching. It was adopted by the Church in the 4th Century, A.D. and opposed by a those who wanted no deviation from scripture.
The name Jehovah appears in the Church of S. Agata Santhia in Italy (Vercelli). It was once a household word. It was removed from the original manuscripts by Trinitarians who deleted it and replaced it with Lord and God. Now people don't know who God is.
Al emplear el nombre “Jehová” nos hemos apegado estrechamente a los textos en las lenguas originales y no hemos seguido la práctica de sustituir el nombre divino, el Tetragrámaton, por títulos como “Señor”, “el Señor”, “Adonay (Adonai)” o “Dios”.
