The name Y####h is sacred in Judaism and cannot be uttered.  Christian worship bandies the name about.  This shows Christianity is in schism from Judaism.  Schism is nasty.  So it is not the legitimate development it claims to be.  And using the sacred name like they are better than Jews shows the level of Christian anti-semitism and passive-aggression.  The Bible sanctions this hate for the Epistle to the Hebrews says that because of Jesus we can know go boldly to God and even into the most holy place.  The implication is that you can now say the name.
