"Administration of the Ordinance Whenever possible, let baptism be administered in a clear lake or running stream. And give to the occasion all the importance and solemnity that can be brought into it. At such a service angels of God are always present. 6T 97"
"And were baptized of him in Jordan, confessing their sins."
Both passages relate to baptism. Matthew 3:6 describes the act of baptism, while EGW discusses the setting and solemnity of the ordinance, including the presence of angels. While not a direct quote, the theme is clearly connected.
"The knowledge of God and of Jesus Christ, expressed in character, is an exaltation above everything that is esteemed in earth or in heaven. It is the very highest education. It is the key that opens the portals of the heavenly city. This knowledge it is God's purpose that all who put on Christ by baptism shall possess. And it is the duty of God's servants to set before these souls the privilege of their high calling in Christ Jesus. 6T 97.1"
"And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent."
EGW directly echoes the sentiment of John 17:3, emphasizing the importance of knowing God and Jesus Christ as the key to eternal life and the highest form of education.
"The one who administers the ordinance of baptism should seek to make it an occasion of solemn, sacred influence upon all spectators. Every ordinance of the church should be so conducted as to be uplifting in its influence. Nothing is to be made common or cheap, or placed on a level with common things. Our churches need to be educated to greater respect and reverence for the sacred service of God. As ministers conduct the services connected with God's worship, so they are educating and training the people. Little acts that educate and train and discipline the soul for eternity are of vast consequence in the uplifting and sanctifying of the church. 6T 97.3"
"Let all things be done decently and in order."
EGW's emphasis on conducting church ordinances with reverence and order directly reflects the principle stated in 1 Corinthians 14:40.
"In every church, baptismal robes should be provided for the candidates. This should not be regarded as a needless outlay of means. It is one of the things required in obedience to the injunction: “Let all things be done decently and in order.” 1 Corinthians 14:40 . 6T 97.4"
"Let all things be done decently and in order."
Ellen White directly references 1 Corinthians 14:40 in this passage.
