I worship the Holy Spirit and I am Christian.
The Trinity has parallels in such disciplines as science (height-width-breadth) or metaphysics (body-mind-soul). These are all signs that one entity can have many different aspects, and that the lines of demarcation are not sharply drawn. Where does the mind leave off and the soul begin? The height and width of an object become its width and breadth when viewed from another angle. And so on.
Muslims take it several degrees farther. Although they deny it, they believe in a Ninety-nine-ity. Allah has 99 names, each describing a different aspect of Allah, yet each one describes Him completely. Muslims can direct their prayers to Allah (God), the Most Compassionate (ar-Rahman), the Most Merciful (ar-Raheem), or any other of a list of names, ranging from the Loving to the Just. This would not be a problem, except that Muslims look upon Christians with contempt for viewing God in much the same way.
When a Muslims worships ar-Rahman instead of Allah, it is plain to him or her that ar-Rahman and Allah are the same. Yet when a Christian directs prayers to Jesus or the Holy Spirit (also just different aspects of the One God), then we are laughingly accused of polythesism. To those Muslims, I ask you to examine your own religion. You have merely pared the number of Arabic gods from 360 to 99.
This is how I think of the Trinity. I *think* the original concept comes from C.S. Lewis, but I can't remember the specifics as he originally wrote them, so my explanation is mere paraphrasing at best.
The Holy Spirit is what pushes you to pray. It is the motivating force. Jesus Christ is who teaches us how to pray. He is the active force. God the Father is who our prayers are directed. He is the receptive force. Each one is fully God, yet each plays a different role in bringing us closer to Him.
If you're Muslim, what pushes you to pray (besides fear and a recorded loudspeaker voice)? Most would answer Allah. Who teaches you to pray? Muhammad, but the prophet learned how to pray from Allah, so again, the answer is Allah. And who is receiving your prayers? Allah. But in each case, Allah is playing a different role, either pushing you or teaching you or receiving the prayers.
To sum up, how is praying in the name of the Father and of the Son and of the Holy Spirit any different from praying in the name of Allah, most Gracious, most Merciful (especially when 96 more aspects of Allah could be added here)?
