"Christianity makes a strong bond of union between master and slave, king and subject, the gospel minister and the degraded sinner who has found in Christ cleansing from sin. They have been washed in the same blood, quickened by the same Spirit; and they are made one in Christ Jesus. AA 460.1"
"There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus."
The EGW passage directly echoes the sentiment of Galatians 3:28, emphasizing the unity and equality found in Christ, regardless of social status or background. The EGW passage uses similar language (master and slave, king and subject) to illustrate this point, making it a clear allusion to the verse.
"For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit."
Both passages emphasize the unifying power of the Spirit and Christ, breaking down social barriers. EGW's passage expands on the implications of this unity, specifically mentioning master/slave, king/subject, etc., which are alluded to in 1 Corinthians 12:13 with the phrase 'bond or free'.
"But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ."
Both passages highlight the idea of being brought near to God through the blood of Christ. EGW's passage speaks of cleansing from sin, while Ephesians 2:13 speaks of being made nigh. The connection is thematic, focusing on reconciliation and closeness to God through Christ's sacrifice.
