Constitutionally Australia embraces religious pluralism. The Christian Church does not make the laws of the land.
Marriage for (most) Christians is a sacrament of the love God has for his Church, however it as at the same time a social contract acknowledged ubder the law of the land.
The Church in so far as it operates inside the law of the land is required not to ignore marriages conducted outside its norms however is not required to reunderstand marriage within its own community of faith.
God is not bound by human law, neither does God need to affirm his rights and copyright under human law.
Which contract came first?, the land or God's from the very moment he declared marriage as his very own institution, under his Created Rights Laws, from the instant he created them male and female, in the Genesis 1:27-28 account?
So, now all of a sudden man wants to amend God's contract and assume authority over the legality of marriage, when man does not have authority to stray from that contract, which is tied to humanities very existence, owing to God placing his Image, that is his LOGO, to seal that contract, which is enforceable on water, under the water, on land and in the cosmos.
What mind would try to dare change the terms, when no land was there at creation to be party to any mutually agreeable change to the original contract that God dictated upon all of humanity.
To change a contract, one must be party to it, as an equal, in mutual agreement or disagreement and as a result coming to reconciliation, through amending the contract, with the intended purpose to come to a mutual agreement.
In the Genesis account, there is no other human party and no mutual agreement involving humans, to make amendment of what is unchangable under the original contract, that
only the Trinity was party to. Since that contract was witnessed by two, as in "Let us make mankind in our image, in our likeness" (Genesis 1:26)
To put in place Marriage Laws of the land in these recent years, that are contrary to the original contract, would be in breach of the original contract and the land that makes such an illegal and none binding contract, is a land like Sodom and Gomorrah, that must come under judgement, where God's right is to destroy to it, to its very end.
In this regard, the land, regardless of what land it is, has become Sodom and in this respect, is now in breach of the original contract and has become a lawless terrorist state, harbouring enemies that pirate and steal from God. Stealing from God what is clearly declared as being God's proprietary owned intellectual property that had been witnessed by two other co-equal members of the Trinity, as a binding ratified contract that is unrevocable and is unalterable by human parties, regardless of what land laws have to say.
Prophesying Christians ought to know what they are doing, when supporting the amendment of the laws of the land that come into direct conflict and breach of the original contract tied to the creation of humanity. In fact such argument to make the law of the land mutually coequal to the Trinity's contract, is an act of defiance and will be considered by God as a treasonous act and you can take this statement to the bank.
Back the law of the land and you are batting against the Trinity.
Good luck with that! Because you know what is coming.
Someone mockingly said, well, "the sky hasn't fallen", and I say YET!
But if people want to bat against the Trinity, then their choice will become the outcome of their eternal security. Yet to teach others to go against the Created Rights Laws of God, that were ratified by the Trinity, is something unheard of!
