All are seperate beings come together in unity to create the trinity.

"Say: He is Allah (God), the One and Only; Allah, the Eternal, Absolute; He begetteth not, nor is He begotten; And there is none like unto Him." [The Noble Quran 112] [Mar 12:29] Jesus answered, "The most important is, 'Hear, O Israel, the Lord OUR God is ONE Lord” (Bible)

When Jesus said that he and his Father are one, he clarified that it was one as in agreement(1Cor 1:10) by showing that he would like for his followers to be one as him and his Father are one (John 10:30; 17:21,22). John 8:16-18 shows that him and his Father were two separate individuals, just like Paul and Apollos were two individuals, but one in purpose (1Cor 3:5-9), or a husband and wife, though different in power, wisdom, and age are one (Mark 10:6-9 http://www.biblegateway.com/passage/?search=1Cor 1:10; John 10:30 ;John17:21-22 ;1Cor 3:5-9 ;Mark 10:6-9;&version=49;15;77;16;51 The following link includes some of what is below along with additional scriptures. http://www.answerbag.com/a_view/7112409 Jesus showed that they are 2 distinct individuals. John 8:16-18 "And yet if I do judge, my judgment is truthful, because I am not alone, but the Father who sent me is with me. Also, in YOUR own Law it is written, ‘The witness of two men is true. I am one that bears witness about myself, and the Father who sent me bears witness about me." . They are one in purpose though, and Jesus clarified the meaning for us at John 17:11 and John 17:21. (John 10:30; John 17:11,21; 1Cor 1:10; Phil 2:2 just like a husband and wife, although two individuals, are one, (Mat 19:5) and Paul and Apolis are one, (1Cor 3:6-9) the people before God confused their language at Babel were one, (Gen 11:6-7) and just like all of his followers should be one.
