The sacraments are the Catholic way of spiritual advancement, especially salvation. It is acknowledged that non-sacramental salvation and advancement is possible and wide spread. Therefore what difference do the sacraments make? One theory is that sacraments of a valid linage offer not just spiritual advancement in the human Christ, but they extend advancement into the divine Christ. The sustained supernatural, divine works of the Churches with valid sacraments offer evidence in the forms of miracles, prophecy and divine visitations.
