"The controversy over resurrection, then, proved critical in shaping the Christian movement into an institutional religion. All Christians agreed in principle that only Christ himself--or God--can be the ultimate source of spiritual authority. But the immediate question, of course, was the practical one: Who, in the present, administers that authority? Valentinus and his followers answered: Whoever comes into direct, personal contact with the "living One." They argued that only one's own experience offers the ultimate criterion of truth, taking precedence over all secondhand testimony and all tradition--even gnostic tradition! They celebrated every form of creative invention as evidence that a person has become spiritually alive. On this theory, the structure of authority can never be fixed into an institutional framework: it must remain spontaneous, charismatic, and open."
