"The heart in which the love of Christ abides will constantly manifest more and more refinement; for the spring of life is love to God and man. Christ is Christianity. This is glory to God in the highest, and on earth peace, good will toward men. This is the carrying out of God's purpose. GW 282.4"
"Glory to God in the highest, and on earth peace, good will toward men."
EGW directly quotes Luke 2:14, making this an explicit allusion.
