Question

What is the holy trinity? How does it affect the lifestyles of Christians in the modern world?

Answer 1

The Holy Trinity is one God but he has three parts. The Father the Son and the Holy Spirit. It doesn't really affect the lifestyles of Christians, When they say God they mean all three of him. It does sound confusing but I know this because I am Christian.

Answer 2

The Holy Trinity is the Christian God. Christians believe that God has three entities: the Father, the Son (Jesus) and the Holy spirit.

Celbrating God as a Trinity influences for example the celebrations, as some (Christimas, etc) are devoted to the Son while others (Pentecost) to the Holy Spirit.
