Is Christianity a belief system based on Monotheism or Tritheism or Hybrid or Neither

Is Christianity a belief system based on Monotheism or Tritheism or Hybrid or Neither Both?

Monothesim. One God in three separate but equal parts Father, Son, Holy Spirt. Making the Trinity.

Convoluted confusing answer: Trinitarian monotheism.
Explanation: Some forms of Christianity reject the Godhead (trinity), and follow monotheism. However, those who have a Holy Trinity (Father/son/ghost) are triathletes. Technically they don't have three gods, however, and I think that form of Christianity is closest to polytheism. The existence of a negative god, or Satan, lends itself to any polytheist religion.

The most accurate answer is probably to describe Christianity as Trinitarian Monotheism. We don't believe there are 3 Gods, but rather one God with three modes. Its a difficult concepts to understand, and deserves a better explanation than space here can provide.

Monotheism. Always has been.
