So how many gods are there in Christendom?

Christendom refers to the collective group of Christian denominations, so the answer to this question will depend on which denomination is being referred to. Generally speaking, the majority of Christian denominations believe in one God, as stated in the Nicene Creed, which reads: "We believe in one God, the Father, the Almighty, maker of heaven and earth, of all that is, seen and unseen." However, some denominations, such as the Unitarian Universalists, believe in a concept of God that is more inclusive and open to interpretation.

In the Roman Catholic and Eastern Orthodox churches, there is a belief in the Holy Trinity, which is composed of God the Father, God the Son, and God the Holy Spirit. All three persons of the Trinity are seen as distinct persons who are united in one divine being.

The Anglican Church also teaches the doctrine of the Trinity, but it does not necessarily see the three persons as being of the same substance.

Protestant denominations generally believe in the Trinity, but they differ in their interpretation of the doctrine. Some, such as Lutherans, Calvinists, and Reformed churches, believe in the doctrine of the Trinity as a unified being, while others, such as Baptists and Methodists, believe in a more open interpretation of the Trinity.

In conclusion, the number of gods in Christendom depends on which denomination is being referred to. Generally speaking, the majority of Christian denominations believe in one God, while some denominations believe in a concept of God that is more inclusive and open to interpretation. Additionally, most denominations believe in the doctrine of the Trinity, although there are some differences in interpretation.
