This is not relativism because there is God, and we live in God's creation: God's creation is truth.
Relativism, by contrast, asserts no God-creator and discovers no truth.
Neither is reality discovered (or dictated!) by "science"; because the nature and operations of "science" is itself a choice.
Therefore there is only a single 'truth' - which is God's creation - and the primary choice is whether to live in God's creation or someplace else.
That is the main truth we create by our thinking.
And apparently, as of 2021, most Man have thought themselves out of God's creation; by thinking themselves things that are not a part of God's creation - not coherent with God's purposes.
In early childhood and in past eras; Man's thinking was largely passive and unchosen; but for modern Man from adolescence on there is choice: we choose what we think.
Choice for modern Man is indeed unavoidable, hence the choice just-is moral, a value, a responsibility.
Each Man is now becoming his own creation - therefore, the big question is (or should be) whether this creation is harmonious with divine creation; and with the creation of those Men who have chosen to take the side of divine creation; or whether a Man's self-creation will be Something Else. Something that is Not divine creation.
This might, in principle, be an unique, isolated, personal creation - each Man as God of his own universe, consisting only of him-self. In practice; this almost never happens (and if/when it does ever happen, we would not know about it.)
Or, Men might reject divine creation and instead join-with the sub-creations of Satan and the demons.
These are sub-creations, because they are 'within' divine creation; and are using that which God has created - but turned against the purposes of God and disharmonious/ dissonant with divine creation.
Hell-on-earth is therefore a concept to describe these anti-God sub-creations - which are now mainstream, official, and increasingly mandatory.
An example of a hellish subcreation is the belief that a man might really become a woman (and in reverse, or back and forth as desired). Modern Man is such that the the thinking creates the reality - so that our culture is set-up to create, sustain and enforce the thinking that actual change of sex is real. Many people here-and-now live in this thought-reality - a reality in which sex change is a 'fact'.
So, on the one hand, 'trans reality' (a world in which trans is a factual reality) is a 'real' reality; but on the other hand it is not divine reality - it is nether a part-of nor harmonious with God's aims or God's plans.
This can be seen from the observation that insisting on 'the fact of trans' subverts and makes-incoherent many other 'factual' aspects of reality; it is subversive and indeed inversional of many values and beliefs that are part of Christian hopes and aims.
Because facts are not isolatable - every-thing is connected, every 'fact' links with reality; so to think a fact inconsistent with divine creation is to reject creation, and to dwell in a sub-creation. And while God's creation is coherent, sub-creations are not.
Sub-creations are incoherent for many reasons - but mainly because of their motivation; which is against God and the coherence of divine creation. The desire for a self-created reality - which, I repeat, is now not just a possibility but an inevitable fact of our modern existence - is therefore divisible into the choice of God's creation or the rejection or God's creation.
Modern Man can therefore think, and make, a reality in which sex change is 'really-real'; but trans reality is not some isolated 'fact', but is indeed linked with an entire sub-created reality that is intrinsically hostile to God's creation.
In other words, to make trans 'really'-real entails making our sub-created reality dissonant with God's creation and hostile to the aims of God.
Man can make trans real by Man's thinking; but the reality in which trans is real is outwith God's created reality.
(This is ultimately why hellish realities are not creative, including not procreative. Since the only reality we all inhabit is God's creation; any Being that goes against God's creation cannot be truly creative because he cannot contribute to God's ongoing creation. Only one who shares the aims and methods of God's creation can coherently contribute to God's ongoing creation. This sharing of aims and methods is a consequence of what is termed Love. Thus only one who loves first God and creation, and then his fellow Men in context of that divine purpose, can be truly - that is primarily - creative.)
On the other side, to take the side of God and to embrace the aims of divine creation, are also active personal choices.
We must Now choose to think God's truth, just as we must choose to think Satan's untruth. Always there will be, will have-been, choice; and therefore responsibility.
Traditional Christian ideas that put the initiative of belief on God's side, and see Man as naturally Christian and passively able to absorb God's truth; and which see obedience to externally-defined God's truth as the primary virtue - are not longer applicable.
A passive and obedient attitude will nowadays absorb and follow the anti-Christian System that rules this world; and Men will then (as they mostly do, apparently) think one or another version of that anti-God sub-created reality which is currently mainstream and mandatory.
And this choice of God's truth is active, it comes from each-of-us as an unique individual endowed with the divine capacity of agency, or free will. We cannot escape the fact of this capacity!
We can think, and believe, whatever we wish; even against the consensus of nearly the whole world. Indeed we will think and believe what we have-wished; and we will ourselves live the consequences of our thinking.
The responsibility is unavoidable - potentially a great gift: the greatest imaginable, to participate actively in God's creation, for eternity; potentially a hellish curse.
Most Men appear to have rejected the divine great gift and to have chosen Hell; by choosing to think/ to make-real/ to make a Reality in which the thought-thing is real - that which is incompatible with the motives of divine creation.
