Does one mean that Bahaullah was G-d?
Please state it unambiguously.
Regards
If you mean the physical body of Bahaullah, no, he is mirza Hussein ali. If you mean the spiritual reality of Bahaullah then, He was the spirit of God. Thus, Bahais make no distinction between God, and Bahaullah. It is not ambiguous. Bahaullah chose Abdulbaha means God chose Abdulbaha. God had manifested Himself in the person of Bahaullah, at all the times, and Spoke through Him.
Muhammad had also spoke these words:
Allah Most High says: "He who is hostile to a friend of Mine I declare war against. My slave approaches Me with nothing more beloved to Me than what I have made obligatory upon him, and My slave keeps drawing nearer to Me with voluntary works until I love him.
And when I love him, I am his hearing with which he hears, his sight with which he sees, his hand with which he seizes, and his foot with which he walks. If he asks me, I will surely give to him, and if he seeks refuge in Me, I will surely protect him" (Fath al-Bari, 11.34041, hadith 6502); This hadith was related by Imam Bukhari, Ahmad ibn Hanbal, al-Bayhaqi, and others with multiple contiguous chains of transmission, and is sahih.
And when Bahais speak to Bahaullah for His commemoration, They read the visitation Tablet. Part of the Tablet reads:
"I bear witness that he who hath known Thee hath known God, and he who hath attained unto Thy presence hath attained unto the presence of God. Great, therefore, is the blessedness of him who hath believed in Thee, and in Thy signs, and hath humbled himself before Thy sovereignty, and hath been honored with meeting Thee, and hath attained the good pleasure of Thy will, and circled around Thee, and stood before Thy throne. " Bahaullah- Tablet of visitation
Isn't this clear enough?
Now, let me, make it more clear. Mirza Hussein Ali became God. He did not choose to become God. But God chose to manifest Himself in Mirza Hussein Ali.
