"No occasion should be given to unbelievers to reproach our faith. We are considered odd and singular, and should not take a course to lead unbelievers to think us more so than our faith requires us to be. 1T 420.2"
"Give none offence, neither to the Jews, nor to the Gentiles, nor to the church of God:"
Both passages address the importance of avoiding actions that could cause others to stumble or reproach the faith. The EGW passage directly applies the principle of avoiding offense to unbelievers, similar to Paul's instruction to avoid offense to Jews, Gentiles, and the church.
