"has been supposed, and that a little concession on our part will bring us into a better understanding with Rome. The time was when Protestants placed a high value upon the liberty of conscience which had been so dearly purchased. They taught their children to abhor popery and held that to seek harmony with Rome would be disloyalty to God. But how widely different are the sentiments now expressed! GC 563.1"
"I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel: Which is not another; but there be some that trouble you, and would pervert the gospel of Christ. But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed. As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed."
Both passages address the danger of straying from the true gospel/faith. Galatians warns against accepting a different gospel, while EGW warns against compromising with Roman Catholicism. The core theme of remaining true to the original faith is present in both.
"The defenders of the papacy declare that the church has been maligned, and the Protestant world are inclined to accept the statement. Many urge that it is unjust to judge the church of today by the abominations and absurdities that marked her reign during the centuries of ignorance and darkness. They excuse her horrible cruelty as the result of the barbarism of the times and plead that the influence of modern civilization has changed her sentiments. GC 563.2"
"Knowing this first, that there shall come in the last days scoffers, walking after their own lusts, And saying, Where is the promise of his coming? for since the fathers fell asleep, all things continue as they were from the beginning of the creation."
Both passages address a denial of past wrongdoings or a dismissal of warnings, with a focus on a perceived complacency or lack of concern about future consequences. The EGW passage speaks to excusing the papacy's past, while 2 Peter speaks to scoffers denying the promise of Christ's return.
