The Buddhists who are not atheists are not adhering to traditional Buddhism. Atheism just means a lack of belief in God and from what I have gathered, there are no gods in traditional Buddhism, but I am sure with the amount of Westerners trying new age religions, they managed to insert a god into their version of the religion.
But if we walk in the light, as He is in the light, we have fellowship with one another, and the blood of Jesus, His Son, purifies us from all sin.
