At times, when a small group of men entrusted with the general management of the work have, in the name of the General Conference, sought to carry out unwise plans and to restrict God's work, I have said that I could no longer regard the voice of the General Conference, represented by these few men, as the voice of God. But this is not saying that the decisions of a General Conference composed of an assembly of duly appointed, representative men from all parts of the field, should not be respected. God has ordained that the representatives of His church from all parts of the earth, when assembled in a General Conference, shall have authority. The error that some are in danger of committing, is in giving to the mind and judgment of one man, or of a small group of men, the full measure of authority and influence that God has vested in His church, in the judgment and voice of the General Conference assembled to plan for the prosperity and advancement of His work.

"And the apostles and elders came together for to consider of this matter."
The EGW quote describes a General Conference making decisions, which parallels the council of apostles and elders in Acts 15. While not a direct quote or explicit allusion, the thematic similarity of a representative body making decisions for the church is present.
"For as the body is one, and hath many members, and all the members of that one body, being many, are one body: so also is Christ."
The EGW quote discusses the importance of the collective body (General Conference) rather than a single person or small group, which aligns with the concept of the body of Christ having many members working together in 1 Corinthians 12:12. The connection is not explicit, but the underlying principle of unity and diverse roles within a body is present.
