The 1(a) position is consistent with the “microcosm” theory of the Church. Mission work would consist primarily of demonstrating the superiority of microcosm life and inviting the macrocosmic outsiders to join, rather than extending the benefits of that better life directly into the macrocosm.

2(a) leading to 2(b) is the traditional Christian theory: salvation via profession of faith results in regeneration, which in turn enables the believer to act in selfless benevolence toward others, and especially toward fellow believers. One could certainly imagine an inversion: actively participating in selfless benevolence constitutes evidence of regeneration, which may eventually lead the regenerate soul to a conscious recognition of Christ’s role in the matter.
