There have been several responses to Lance Simmons' posting about Jesus' humanity.
None seems to have taken into account the historical standards.
I'm going to be speaking from the perspective of discussions in the 4th through 6th Centuries. Protestants generally accept the early ecumenical councils. If there are later doctrinal developments in the Roman Catholic Church, this posting will not take them into account. We are not persons prior to being human persons. This position is clearly taught by Athanasius.
