"The situation was critical. The evils that had been introduced threatened speedily to destroy the Galatian churches. AA 383.2"
"I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel:"
Both passages refer to problems within the Galatian churches. Galatians 1:6 expresses Paul's dismay at their turning away from the true gospel, while the EGW passage describes the situation as 'critical' due to introduced evils.
"But I fear, lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ."
Both passages deal with the corruption of faith and the introduction of evil influences. The EGW passage speaks of the destruction of the Galatian churches, while the verse warns of corruption from the simplicity in Christ, similar to the serpent's deception of Eve.
"Paul was cut to the heart, and his soul was stirred by this open apostasy on the part of those to whom he had faithfully taught the principles of the gospel. He immediately wrote to the deluded believers, exposing the false theories that they had accepted and with great severity rebuking those who were departing from the faith. After saluting the Galatians in the words, “Grace be to you and peace from God the Father, and from our Lord Jesus Christ,” he addressed to them these words of sharp reproof: AA 383.3"
"For out of much affliction and anguish of heart I wrote unto you with many tears; not that ye should be grieved, but that ye might know the love which I have more abundantly unto you."
Both passages describe Paul's emotional distress and his writing to believers with severity and love. The EGW passage describes Paul's reaction to the Galatian apostasy, while the verse speaks of Paul's writing with affliction and anguish of heart.
