"The Christian church was at this time entering upon an important era. The work of proclaiming the gospel message among the Gentiles was now to be prosecuted with vigor; and as a result, the church was to be strengthened by a great ingathering of souls. The apostles who had been appointed to lead out in this work, would be exposed to suspicion, prejudice, and jealousy. Their teachings concerning the breaking down of “the middle wall of partition” [ Ephesians 2:14 .] that had so long separated the Jewish and the Gentile world, would naturally subject them to the charge of heresy; and their authority as ministers of the gospel would be questioned by many zealous, believing Jews. GW 441.2"
"For he is our peace, who hath made both one, and hath broken down the middle wall of partition between us;"
Ellen White directly references Ephesians 2:14 in this passage.
