I was following a sort of Jewish custom since I am Jewish by birth, to answer your first question.
Understood, and I do not want to gratuitously put down gestures of respect to the good Lord. Sometimes it is a cultural matter. Even New Testament copyists would sometimes render the Greek for Lord (kurios), when it referred to Jesus, as KS in a similar spirit, showing among other things that they did view Jesus as God.
The whole concept of holy Trinity is a mind boggler, but ultimately most conventional Jewish rabbis, while disagreeing with the concept, have conceded that a believer in that concept of God remains a monotheist. (It matters with respect to Talmudic regulations as to who can serve a Jewish household without violating ritual prohibitions as the rabbis see it. For certain functions, idolators and polytheists are out.)
The good Lord bless you and keep you.
