Adventistische Schriften über: "What did Ellen White teach about Mother Earth and the Sabbath Queen?"

No relevant passages were found in Ellen White’s writings for your question. Therefore, I cannot substantiate any specific statement she made about “Mother Earth” or the “Sabbath Queen.” However, these terms can be considered in light of her known understanding of the Bible.

“Mother Earth”: Respecting creation, not worshipping it

If “Mother Earth” refers to a divine mother or a force of nature worthy of worship, this contradicts Ellen White’s understanding: God is the personal Creator; the earth is His creation, not a deity itself. The Bible explicitly distinguishes between worshipping the Creator and worshipping what has been created (Romans 1:25).

If, on the other hand, the expression is used merely as a figurative name for our earth, it does not automatically imply religious worship. In keeping with her writings, people should treat nature with care: God has entrusted them with responsibility for His creation (Genesis 2:15). A connection with nature and environmental protection should therefore be distinguished from the deification of nature.

“Sabbath Queen”: Figurative language, not a divine person

The term “Sabbath Queen” comes from Jewish Sabbath tradition. In that tradition, the Sabbath is figuratively welcomed like a queen or bride. This poetic personification does not necessarily mean that a goddess is being worshipped.

Ellen White understood the Sabbath as the seventh day, blessed and sanctified by God: a memorial of creation and a time of rest, worship, and fellowship with God (Genesis 2:2–3; Exodus 20:8–11). The Sabbath is not a distinct heavenly person. At its center is the Lord of the Sabbath, Jesus Christ (Mark 2:27–28).

In summary: According to her principles, we should care for the earth as God’s creation and respect the Sabbath as God’s holy time—without deifying either the earth or the Sabbath. I cannot substantiate any particular teaching of Ellen White that connects “Mother Earth” and the “Sabbath Queen.”
