It is not always remembered that the key gesture of Christianity is the willing existence as a host for the body of Christ. Christians invite Christ into their hearts when they convert, and from then on, in principle, their individual personhood and ends are subordinate to a new person who collectively lives in all of them: Christ. In the best case, the practical result is a heightened state or connectedness, a joy in fellowship, a tendency towards courageous self-sacrifice - along with a real phenomenological experience of Christ-consciousness, an intimate relationship with an actual divine being.
There is a secularised version of the body of Christ that (implicitly or explicitly) drives most humanist and radical politics. The consciousness of the revolutionary community that overturns established values, aims with their faith at seemingly impossible transformations, has freed their desire from the snares of the fallen world and now desires only love, willing to suffer in the name of the dignity of every human being, no matter how low on the social totem pole.
It is ironic that this latter secularized vestige of Christ (often unavowed) is far truer to the message of Christianity than the avowed version in which the Church participates. The 'official' body of Christ coexists easily with class, race, gender oppression - this is almost too obvious to merit pointing out.
Nevertheless, the secularized version is existentially extremely meager. There is no asceticism in it and it lacks the key features of joy and personal transformation. It also lacks power.
To unify these two experiences of the body of Christ - one that is genuinely emancipatory on the social level and one that is genuinely transformative at the individual level - this is an important aspect of DEONTOLOGY.
It seems this would require accurate knowledge of what is going on in the authentic Christian experience and then transposing it into the emancipatory project. The 'faith' invoked in leftist politics is laughable - it a pale imitation of the real thing. The ends of emancipation deserve to be met with actual divine power.
