“I tell you; this man went down to his house justified, rather than the other.” Luke 18:14a ESV1
There is a protocol for greeting a member of the English Royal Family:
“When being presented to The King or Queen, men are expected to bow from the neck. Women can either bow or curtsey. If a curtsy is given it is just a short bob, keeping the back straight, hands by the side, dropping the knees slightly and bowing the head … Allow The King or The Queen to begin, steer and end the conversation.
On first address: Your Majesty
Thereafter: Sir (King) or Ma’am (Queen).2
There is a proper way to address the President of the United States.
“In direct oral address – actually speaking to the President – the President is addressed as: Mr. President—His given name or surname are not used in his presence. This pattern of not using the name is typical around the world when addressing the highest officials—chiefs of state, heads of government, speakers of houses, chief justices, and a very few others.”3
There is also an appropriate way to come before the King of the Universe.
