How is the trinity monotheistic?

The trinity is both polytheistic and monotheistic. In Islam, there is not this problem, because there is no god but Allah. But Christianity is incoherent because of the trinity.

Monotheism: the doctrine of belief that there is but one God.
Polytheism: belief in or worship of more than one god.

According to the first plank of the doctrine of the trinity, it is Monotheistic in every sense of the word, as Tim says. However, according to the second and third plank, the trinity is Polytheistic in every sense of the word (Father god, Son god, Holy Spirit god. Each distinct.) That is three. Three is more than one.

To accept Christianity is to accept the trinity. To accept the trinity is to accept Polytheism and Monotheism, at the same time, which is to reject Polytheism and Monotheism at the same time. To accept the trinity is to reject the trinity. To accept Christianity is to reject Christianity at the same time.
