The Son and the Holy Spirit are co-eternal with the Father.
For over sixty years I have been enquiring what exactly the Holy Spirit is, no satisfactory answer yet. I got the belt for asking my P5 teacher what the Holy Sprit was, and as she was unable to answer properly, I asked if it did indeed exist, as she could not explain what it was. Religious studies were taken very seriously in the Islands in the 50s. Effectively I was belted for heresy. I feel I may be unique on these boards in that respect.
