How do you say Father Son and Holy spirit in Irish?
an tAthair (the Father), an Mac (the son), an Spiorad Naomh (the Holy Spirit)
The Trinity doctrine teaches that the Father is the one and only true God. From the Father comes the Son. And from the Father through the Son comes the Holy Spirit. The Son and Spirit are as much God as the Father, they are not separate, but distinct. The Son is not the Father or Spirit and the Spirit is not the Father.
The Father is the only true God. The Son (or Logos) came from the Father, and the Holy Spirit comes through the Son. The Father is not the Son nor the Holy Spirit. Think of the workings of the Sun. The Father is like the Sun (as in the star), the Son is like the rays of light that come from the Sun, and the Holy Spirit is like the heat comes through the light.
