A Christian definition of family is "fatherhood." The Greek word in the New Testament translated family is "patria," a word closely akin to "pater" meaning father. Family loyalty is essentially loyalty to father and the honouring of his name.
The Australian Constitution states that the "executive power of the Commonwealth is vested in the Queen and is exercisable by the Governor-General as the Queen's representative, ... (Sec. 61)." This means that the government of the Commonwealth resides in the person of Her Majesty Queen Elizabeth II.
The Constitution prescribes an oath or affirmation of allegiance to the Queen that is to be taken by every senator and every member of the House of Representatives before taking "his" seat (Sec. 42 and SCHEDULE). Allegiance to the Crown makes personal our civil allegiance, in the same way that allegiance to father makes personal our familial allegiance. This implies personal responsibility and integrity on the part of both the civil and familial heads.
George Winterton, in his proposed draft Australian republican constitution, suggested that an oath or affirmation of allegiance be made to "the Commonwealth of Australia." This impersonalizes civil loyalty. How can we give loyalty to fickle and rapidly changing opinions, institutions and whatever else makes up the amorphous body-corporate called: "the Commonwealth of Australia"?
I would contend that our Constitutional Monarchy can only be properly appreciated through Christian eyes, and that some republicans may wish to remove Australia's Christian heritage along with its Christian Monarch.
God save the Queen!
Defend the Constitution!
