I don't accept the trinity either. In Judaism the Holy Spirit simply refers to the power of God.
It is also worth mentioning that God transcends gender. He is neither male nor female (nor an it). He simply doesn't fit into these categories. However, he has attributes that are commonly associated with both male and female.
I feel obliged to tell you that I agree, based on my study of the Scriptures. There's more to it, but from my study and research, I see that the word ruach, and/or spirit, does not refer to one of the three persons of a triune so-called Godhead. I also agree that the Almighty God does transcend gender, any depiction of Him as seen by Daniel and other prophets is so that we can better understand Him.
Of course, God Almighty told Moses that if he saw His face, he would die. I'm sure you remember that. Yes, I use the masculine because that makes sense based on what the Bible says. And -- since "He" said, "Let US make man in OUR image," it is obvious HE was talking to -- someone else. But I won't go into that now. PLUS, HE made Adam and then Eve. Two, the female coming from the male's rib. Thanks for bringing up what you did. Of course, there's more to it, and I'm not a Hebrew scholar, but I do try to understand.
