I did a search for an explanation of pentecost - yeah - dumb old me didn't know what it was
One of the results said.
"The commemoration of the coming of the Holy Spirit upon the disciples of Jesus following his ascension, Pentecost is considered the "birthday" of the Christian church. (Acts 2:1-11) It comes 50 days after Easter (Pascha, Orthodox Easter). Roman Catholic and Protestant Christians observe Pentecost on a different date than Orthodox Christians."
What is an orthodox christian?? I have a vague idea - but would take too long to explain what I think it is......is there a short version?
