Buddhism: Between Unbelief and Spiritual Inquiry

In the context of Abrahamic religions, the position of Buddhists can be interpreted in two ways. On one hand, the arguments of the Abrahamic traditions suggest that disbelief in a Personal God—a central requirement of these religions—categorizes Buddhists as non-believers. For example, the Buddhist catechism explicitly states:
"The concept of a Personal Creator God is nothing but a fabrication borne of human ignorance. Buddhists utterly reject belief in a Personal God and regard the doctrine of creation as a fanciful delusion" (source: link txt, page: 18).

Moreover, in the context of Christian polemics, Buddhists are grouped among those who, by not sharing the faith in the God of Christ, will not experience the glory of Christ:
"The wicked shall not behold Your glory, O Christ—that is, unbelievers, those who believe erroneously, Jews, Muslims, Buddhists, pagans.

And will we behold it?

It depends on our lives, our faith, our piety" (source: link txt, page: 159).

On the other hand, there are arguments that emphasize the spiritual dignity and outstanding wisdom of the Buddha, which allow Buddhism to be seen as a path toward higher truths, albeit one that is markedly different from the monotheistic understanding. One text notes that Jesus listened not only to Brahmins, but also to Buddhists, indicating a recognition of the spiritual authority of Buddhist teaching:
"Jesus listened to Brahmins, Buddhists, and Zoroastrians, and surpassed them all in his wisdom and love for people… A text that once served as an argument for Christians in their polemics against Buddhism now stands as an anti-Christian argument among non-Buddhists" (source: link txt, page: 3127).

Furthermore, the sources themselves emphasize that Buddhism encompasses different forms—from pure atheistic pantheism to a variant that shows traits of a personal expression of the cosmic essence:
"Buddhism has two main forms: the first is an atheistic pantheism, i.e., of an impersonal character, in which events are connected by the notion of necessity; the other form is a pantheism that has acquired features of a personal spirit..." (source: link txt, page: 42).

Thus, from the perspective of the Abrahamic religions—where belief in a Personal God is the cornerstone—Buddhism is often interpreted as a form of unbelief, since its teachings negate that principle. However, Buddhism itself represents a comprehensive spiritual system in which the quest for truth and transcendent experience are the fundamental aims, allowing its adherents to be seen as possessing a deeply rooted faith in higher cosmic laws, albeit in a form that is fundamentally different from the monotheistic worldview.
