At the same time, it also foreshadows both Nate's A God, I Am Not views, and calls back to his expression of absolute faith in her as the Mutant Messiah in the run up to Avengers vs. X-Men. Of course Hope's the Jesus equivalent of mutantkind - that's how Nate sees her.
X-Man doesn't believe he is a god, despite easily having more power than most characters that are referred to as gods. He doesn't even take the In-Universe role of moral guide, leaving that to the dead Charles Xavier, much less Messiah, leaving to the dead Hope. Why? Because he doesn't believe he deserves it. He seems himself as a necessary destroyer, born to end the apocalypse, but not to lead. And why's that? Well, he's been burned in the past by those seeing him as a Messiah, as the incident in New York where the Purple Man manipulated him into becoming the 'Manhattan Marvel', which had horrible consequences for much of his supporting cast. More generally, he's been out on a pedestal and destined to do one thing or another all of his life. It kinda makes sense that he just wants to take a back seat and relax.
X-Man has the ability to rewrite an entire reality's history and sway everyone to his side (to a point), but while "Age of X-Man" En Sabah Nur is easily a thousand times nicer than his counterpart (at first glance, anyway) he still stands in stark opposition to the doctrines Nate has set in place. This is likely not coincidence; even with god-like Reality Warper powers, Nate cannot conceive a reality in which he and Apocalypse are on the same side.
As it turns out, this was intentional, with Apocalypse playing the rebel/villain, drawing disruptive elements to him, where Nate can keep an eye on them - and not only that, but give the X-Men something to fight, which they subconsciously need.
The opposition to familial and romantic relationships makes a lot of sense when you consider Nate's history with both:
His main Love Interest, Threnody, was manipulating and spying on him on Sinister's behalf while also planning to use him against Sinister, addicted to his powers (she fed off death energies, he was both dying and an absurdly powerful psychic). The other two women with whom who he had romantic/sexual relationships in his solo series were outright upfront cases of actual Parental Incest : Maddie Pryor, the deceased clone of his own genetic mother whom he accidentally unconsciously resurrected from the afterlife upon his arrival in the main Marvel universe (it was weird), who was a massive Tsundere, spending half her time seducing him, the other half fighting him, and Queen Jean - an Evil Counterpart of said mother, the real Jean Grey, who pretended to be Maddie as part of a plan to enslave him and use him as a Living Weapon and generalised slave (including sex slave) and he had to kill her in self-defense.
He also never really had a family, save for intermittent encounters with Cable, Jean and Maddie (he got to know and got on with Cyclops later on) - his relationship with Jean was the one that could remotely be called close or stable. Oh, and the closest person he had to a father was his realitys counterpart of the X-Man Forge, his mentor, who was murdered in front of him by his actual creator, his realitys counterpart of mad scientist-supreme Sinister.
In the history of this world the Original 5 X-men are the same with the exception that Nate has taken Beasts place in the team while Beast is in jail. Given how much he hates Dark Beast, this shouldnt be a surprise.
