Romantic and Christian - both are needed.
Christianity comes first, because it is the structure of reality. But without Romanticism... well, "Christianity" does not involve us, each, personally, powerfully.
Without the Romantic and personal involvement, then Christianity is just theory and/or just a social institutions. And, as of here-and-now - such a Not-Romantic Christianity Will Not motivate us sufficiently to resist the pervasive and otherwise-overwhelming evil of our civilization.
On-paper, or legal, or social religion (including Christianity) has been demonstrated to be radically insufficient. Its adherents - no matter how strident! - are actually engaging in mainstream atheist-materialist cultural activities...
Whatever they spout or assert (and no matter of what they have convinced themselves); they Actually Are doing nothing-more than socializing, doing politics, seeking status, or an economic niche, or survival - or pursuing some-other of those things that everybody does, and is encouraged to do, in the mainstream of ideology.
Such theoretically/ legalistic/ institutional Not-Romantic Christianity is literally irrelevant; it is spiritually-indistinguishable from the atheism, agnosticism or anything-but-Christianity spirituality.
Not-Romantic Christianity is no-better than the prevalent values of our society.
And, what this means in practice; is that Non-Romantic Christians will not choose the actuality of salvation after their mortal lives; for the simple reason that there are other things they want more than salvation.
And because they have assimilated the value-inversions and anti-creation values of the actual Western Civilization into-which their churches are thoroughly assimilated.
To recognize this fact, we need to understand that things really were different in the past, because people were intrinsically different.
Romanticism - the need for a personal and passionate engagement with Life; was not really "a thing" at all, until the late 1700s, and did not spread at all widely for another century.
In the more remote past - especially in the Medieval era and before - all religion was "social" in nature; and for Men of that era it was potentially very powerfully motivating. Personal engagement, motivation... these things just-happened, spontaneously - or by passive-acceptance.
Indeed; such religion with such people was for centuries (millennia) the single most powerful motivator in life, such that individuals were extremely courageous in loyalty to their church (in many religions) - men would risk and indeed sacrifice much in adherence to the Christian church.
Even monarchs (certainly not the best of Men!) could be remarkably courageous!
While Henry VIII was a monster of pride, lust and spite; his children (Mary, Elizabeth, Edward VI) all displayed tremendous individual courage and tenacity in pursuit of their religious convictions...
Even when (especially in the case of Mary and Elizabeth) they found themselves isolated, their lives in danger, and with all the powers of the state and institutional church ranged against them - each continued to be loyal to (and risked everything for) what he or she regarded as the true church.
Such motivation is now gone, and long gone; such courage in loyalty to a religious vision is now a thing of the past.
What was an automatic, passive, spontaneous involvement in Christianity - must now actively be sought as a personal necessity, a lifelong quest.
This is necessary if a Christian is to find the motivation necessary to transcend the endemic evils of Western Civilization, 2026.
