"Suddenly the discourse was interrupted by the descent of the Holy Spirit. “While Peter yet spake these words, the Holy Ghost fell on all them which heard the word. And they of the circumcision which believed were astonished, as many as came with Peter, because that on the Gentiles also was poured out the gift of the Holy Ghost. For they heard them speak with tongues, and magnify God. AA 139.1"
"And they of the circumcision which believed were astonished, as many as came with Peter, because that on the Gentiles also was poured out the gift of the Holy Ghost. For they heard them speak with tongues, and magnify God. Then answered Peter,"
The EGW passage directly quotes and references Acts 10:45-46, making it an explicit allusion.
"And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance."
Both passages describe the Holy Spirit falling on believers and them speaking in tongues. While Acts 2:4 is the Pentecost event, the EGW passage refers to a similar event in Acts 10, making this a valid thematic parallel.
"Today God is seeking for souls among the high as well as the lowly. There are many like Cornelius, men whom the Lord desires to connect with His work in the world. Their sympathies are with the Lord's people, but the ties that bind them to the world hold them firmly. It requires moral courage for them to take their position for Christ. Special efforts should be made for these souls, who are in so great danger, because of their responsibilities and associations. AA 139.4"
"For ye see your calling, brethren, how that not many wise men after the flesh, not many mighty, not many noble, are called:"
Both passages discuss God's calling of people from various social strata, including those in positions of power or influence. However, the connection is not a direct quote or explicit allusion, but rather a thematic similarity. The EGW passage uses Cornelius as an example, while 1 Corinthians 1:26 makes a general statement about God's calling.
