In reference to Paul Knitter's Jesus and the Other Names, Catherine Cornille, when addressing Knitter's claim that Jesus is not the "only" savior, comments: "Not only are the religious views of different traditions at times directly opposed or mutually exclusive, but the very claim of ultimacy of one religion necessarily precludes the truth of the claims of others." In reference to Knitter's Without Buddha I Could Not Be a Christian, James L. Fredericks declares: "Nowhere are we given to believe that there are some respects in which Buddhists and Christians are simply baffling to one another because their religious visions are incompatible. I also worry that the more Buddhism is enlisted into service of Christian faith as an ancilla theologiae , the less it seems like Buddhism." In reference to Without Buddha I Could Not Be a Christian, Robert Magliola asserts, in the Journal of the American Academy of Religion that Paul Knitter "is not Catholic enough because he is not Buddhist enough and vice versa." Quoting Francis Xavier Clooney, S.J.'s statement, in Clooney's Jesuit Postmodern that comparisons "seem not to fit into a single, coherent view," Magliola points out that Knitter's proposed "one universal Spirit" perpetuates the outdated modernist notion of "equable holism" or "openness" rather than the "jagged, asymmetrical" nature of reality. In reference to Knitter's contribution as co-author in Paul Knitter and Roger Haight, , Jesus and Buddha: Friends in Conversation, Joseph A. Bracken, S.J., in Catholic Books Review, asserts, countering both Knitter and Haight, that "in ethical reflection one should begin with the recognition of the Otherness of the Other" rather than with "the sustained meditation by the self on one's moral responsibility for others": In reference to Knitter's contribution as co-author of Jesus and Buddha: Friends in Conversation, Robert Magliola, in his review-article in Dilatato Corde, online journal of the Dialogue Interreligieux Monastique / Monastic Interreligious Dialogue, argues against Knitter's "double-belonging" in the following way:
Mahayana Buddhism affirms the Two truths doctrine, mundane truth and Ultimate truth, are mystically identical, i.e., "form is emptiness and emptiness is form." Catholic Christianity, for its part has teachings such as... the presence of God in all things via "essence, presence, and power," but matter and form are never regarded as absolutely identical. Thus, in regard to the Ultimate, Mahayanist affirmation of the absolute identity and Catholic rejection of the absolute identity are two tenets that irreducibly contradict each other.
