The only begotten Son of God

Just wanted to share this conclusive quote from the Spirit of Prophecy showing very plainly (once again) that sister White understood Christ to be the only begotten Son of His Father BEFORE coming to earth in humanity to effect the plan of salvation:

If God could have changed his Law to meet man in his fallen condition, would he not have done this, and retained his only-begotten Son in heaven?--He certainly would. But because his Law was as changeless as his character, he gave his beloved Son, who was above Law, and one with himself, to meet the penalty which his justice demanded.  {ST, February 25, 1897 par. 3}
