Rationality in the Trinity

First of all, I believe that the mystery of the Godhead is beyond human logic.....just as many concepts are beyond human logic.

Please answer this, what "demonstrative proofs" do you have of Islam.  You simply accept it as a matter of faith, right?

As a Christian, I believe God's Word is contained in the Old and New Testaments.  They teach that there is One God - and they also call the Father God, the Son God and the Holy Spirit God.

Thus we define God as One, who manifests as the Person of the Father, the Person of the Son and the Person of the Holy Spirit. Yet, not three gods (as Mormonism teaches), but One God.

Let me give you this example from chemistry.  If you place H2o in a test tube and subject it to certain laboratory environments, the water in the test tube will be liquid, ice and vapor, all simultaneously.  If water, the simples of compounds, can be three simultaneously, while still remaining one substance - why don't you believe that God can do the same?

What proof do I have?

Allah Says in the Qur'an Qul'hu Allahu AHAD, Allahu Samad Lam yalid Wa' Lam Yulad Wa' Lam Yakulahu Kufuwan Ahad

Ask one of the Muslims what this means.....
