To me, marriage is partly a religious thing and I’m not religious.

Campbell frames marriage as an institution that, in his view, still carries a significant religious component—ritual, vows, and moral sanction traditionally mediated by faith communities. By stating he is “not religious,” he signals a personal distance from that framework and implies ambivalence about participating in a practice he associates with belief. The remark can be read as a secular critique: if marriage is culturally coded as sacred, nonbelievers may feel it is not fully “for them” unless reimagined in civil or humanist terms. It also hints at a broader tension in modern societies between inherited religious ceremonies and increasingly secular personal identities.
