The Buddhist world view is monistic. That is, the existence of a personal creator and Lord is denied. The world operates by natural power and law, not divine command. Buddhism denies the existence of a personal God. As Marcus Bach says in 'Had You Been Born In A Another Faith':
Any concept of God was beyond mans grasp and since Buddhism was a practical approach to life, why not deal with practical things? India, where Buddhism was born, had so many Hindu gods that no-one could number them. They were often made in the image of men, but Buddhism was made in the image of concepts about life and how life should be lived. If the truth were known, you often tell yourself, Buddhism has no God in the Hindu or Christian sense, nor does it have a saviour or messiah. It has the Buddha, and he was the Enlightened One, the Shower-Of-the-Way
There is also no such thing in Buddhism as sin against a supreme being. In Christianity sin is ultimately against God although sinful actions also affect man and his world. This necessitates a saviour to deliver man from his sins, whom Christians identify as Jesus Christ.
According to Buddhist belief, man is worthless, having only temporary existence. In Christianity man is of infinite worth, made in the image of God, and will exist eternally. Mans body is a hindrance to the Buddhist while to the Christian it is an instrument for glorifying God. For example, Paul writes to the Corinthian Church:
Do you not know that your body is a temple of the Holy Spirit who is in you, whom you have from God, and that you are not your own?
Buddhism also takes many forms. Consequently, there is a wide variety of belief in the different sects with much that is contradictory. One writer comments, "The rather odd fact is that there is ultimately developed within Buddhism so many forms of religious organization, cultus and belief, such great changes even in the fundamentals of the faith, that one must say Buddhism on the whole is really like Hinduism,a family of religions rather than a single religion." Christianity also takes many forms but all confessing Churches subscribe to the same basic creeds, statements of faith formulated in the early centuries of the Church which have always been upheld by Christians.
Finally, while the Bible tells Christians to 'test all things' (1 Thess. 5.21-22) Buddhism in many of its forms, eg Zen, mocks critical analysis.
