"At Battle Creek The General Conference was held at Battle Creek, October 2-14, 1878. More than forty ministers were present. We were all happy to meet here Elders Andrews and Bourdeau from Europe, and Elder Loughborough from California. At this meeting was represented the cause in Europe, California, Texas, Alabama, Virginia, Dakota, Colorado, and in all of the Northern States from Maine to Nebraska. LS 238"
"And the apostles and elders came together for to consider of this matter."
Both passages describe gatherings of religious leaders to discuss important matters. However, the EGW passage is simply a description of a meeting, while Acts 15:6 describes a pivotal council. The connection is thematic, but not strong.
"On Wednesday of the second week of the meeting, a few of us united in prayer for a sister who was afflicted with despondency. While praying, I was greatly blessed. The Lord seemed very near. I was taken off in a vision of God's glory, and shown many things. LS 238.3"
"And when they had prayed, the place was shaken where they were assembled together; and they were all filled with the Holy Ghost, and they spake the word of God with boldness."
Both passages describe prayer meetings followed by a manifestation of God's presence (vision in EGW, Holy Spirit in Acts). The connection is thematic, though not a direct quote or explicit allusion.
"Confess your faults one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much."
Both passages emphasize the power of prayer, particularly when offered for the healing or well-being of others. James 5:16 speaks to the efficacy of prayer, and the EGW passage describes a prayer meeting for a sister's despondency, resulting in a blessing and vision.
"These were meetings of solemn power and of the deepest interest. Several connected with our Office of publication were convicted, and converted to the truth, and bore clear, intelligent testimonies. Infidels were convicted, and took their stand under the banner of Prince Immanuel. This meeting was a decided victory. One hundred and twelve were baptized before its close. LS 238.4"
"Then they that gladly received his word were baptized: and the same day there were added unto them about three thousand souls."
Both passages describe a successful evangelistic effort resulting in numerous baptisms. The EGW passage mentions 112 baptisms, while Acts 2:41 mentions about 3000. The parallel lies in the outcome of conversions and baptisms following a period of preaching.
