I think it's on topic because I think it's intrinsic to S6. 🙂 In fact, the season finishes on Spike receiving his soul.
I don't think there's any "perhaps" about it. 🙂
We sometimes use them - Agape, for instance, is latinised as Caritas, anglicized as Charity. But, who defines these terms (I think St Augustine had a lot to do with synthesizing Greek and biblical love)? Where are the female Greek philosophers, the female Popes, the women bishops? The great women poets, playwrights and novelists? Yeah...I know we have them now but that's not always been the case. Traditionally, it's men who've told us, explained to us, described what love is. Would Shakespeare's sister (not the group) have experienced love, written about love, in quite the same way as her brother, William? Is a mother's love for a child the same as a father's? I'm not according value - I'm asking if a "universal context" actually exist? This isn't going off topic because, IMO, this is what underpins S6 (and 7) and (again, IMO) it's one of the reasons we shouldn't underrate the later seasons.
