"In our schools the work of teaching the Scriptures to the youth is not to be left wholly with one teacher for a long series of years. The Bible teacher may be well able to present the truth, and yet it is not the best experience for the students that their study of the word of God should be directed by one man only, term after term and year after year. Different teachers should have a part in the work, even though they may not all have so full an understanding of the Scriptures. If several in our larger schools unite in the work of teaching the Scriptures, the students may thus have the benefit of the talents of several. CT 432.1"
"Now there are diversities of gifts, but the same Spirit."
The EGW quote discusses the benefit of diverse teachers and talents, mirroring the Bible verse about diverse gifts from the same Spirit. The connection is valid and meaningful.
"Why do we need a Matthew, a Mark, a Luke, a John, a Paul, and all the writers who have borne testimony in regard to the life and ministry of the Saviour? Why could not one of the disciples have written a complete record and thus have given us a connected account of Christ's earthly life? Why does one writer bring in points that another does not mention? Why, if these points are essential, did not all these writers mention them? It is because the minds of men differ. Not all comprehend things in exactly the same way. Certain Scripture truths appeal much more strongly to the minds of some than of others. CT 432.2"
"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."
EGW uses the example of multiple Gospel writers to illustrate how different perspectives contribute to a fuller understanding, which aligns with the concept of diverse members forming one body in Christ.
"The same principle applies to speakers. One dwells at considerable length on points that others would pass by quickly or not mention at all. The whole truth is presented more clearly by several than by one. The Gospels differ, but the records of all blend in one harmonious whole. CT 432.3"
"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."
This passage continues the thought from the previous one, further solidifying the connection to the idea of unity in diversity, as represented by the body of Christ.
