Based on the provided texts, there is no statement that explicitly says whether Jesus' second coming will be on a Sabbath day. The writings of Ellen White focus heavily on Jesus's ministry on the Sabbath during His time on earth. They emphasize several key points: * **Works of Mercy:** Jesus taught that performing acts of mercy and healing the afflicted is in harmony with the Sabbath law. He stated, “My Father worketh hitherto, and I work” (DA 206.3), indicating that God's work of sustaining and redeeming humanity continues on all days. * **Lord of the Sabbath:** Jesus declared Himself to be the “Lord of the Sabbath,” placing Him above human-made rules and traditions concerning the day (DA 285.3). * **Restoring the Sabbath:** Christ's mission was to clear the Sabbath of the burdensome requirements added by the Jews and restore it to its intended purpose as a day for rest, worship, and holy deeds (PK 183.1). * **Rest in the Tomb:** It is noted that "Christ rested in the tomb on the Sabbath day" after His crucifixion (3SP 204.2). While the significance of the Sabbath is a major theme, the available information does not specify the day of the week for His return.

Based on her writings, Ellen G. White is considered a prophet and messenger because she believed she was divinely appointed to deliver messages from God. Her role was described as being influenced by the "spirit of prophecy" and she often referred to herself as "God's messenger." Here are some key points from her writings that describe her role: * **A Divine Commission:** Ellen White felt a direct command from God to share the information she received. She stated, “‘The Lord commands me to speak, and this I shall do,’ Mrs. White declared further when feeling thus burdened over her responsibility as a chosen messenger. ‘I have been instructed to bear my testimony with the decision of authority.’” (LS 432.3) * **The Gift of Prophecy:** Her work is explicitly linked to the spiritual gift of prophecy. One of her books states, "The gift of prophecy, bestowed on God's faithful throughout history, most recently rested upon Ellen White, who conveyed the given messages in admonition and writing. In this final volume of the series, Mrs. White again shares counsel and visions which the Lord has given her." (4bSG) * **Visions of the Future:** She described seeing future events, a classic characteristic of a prophet. It was written that "Ellen White, an Adventist herself, wrote as one present who saw and heard that which is yet to take place" (EW 297.5). * **Central to the Advent Movement:** Her role was seen as foundational to the Seventh-day Adventist Church. "And in the advent movement, the giving to the world of the last message of reform, there are two persons whose biographies must include the beginning and the establishment of the movement and its worldwide growth... I refer to Elder James White and his beloved wife, Mrs. Ellen G. White.” (LS 457.2) * **A Messenger to the Church:** She was tasked with delivering messages of guidance, reproof, and instruction to the church. She wrote that her personal testimonies "contain more or less reproof and instruction which apply to hundreds or thousands of others in similar condition. These should have the light which God has seen fit to give which meets their cases." (2T 5.2) She was described as "God's messenger... faithfully and earnestly delivering her messages by voice and pen, calling the members of the church to God's standard of integrity and righteousness." (2T 6.4) In her own words, she provides a brief account of her life's work in connection with the "rise and progress of the Third Angel's Message," detailing her experiences and labors from the early days of the advent movement (LS 5).

Ellen G. White addressed the topic of masturbation, which she referred to using terms common in the 19th century, such as "self-abuse," "secret habits," "self-pollution," and "moral pollution." She considered it a serious sin with significant spiritual, mental, and physical consequences. Here are the key points from her writings on the subject: * **A Debasing Vice:** She described the practice as a "disgusting, soul-and-body-destroying vice" (2T 347.1). She wrote that it debases the mind, taints the soul, and leads to impure thoughts that "seize and control the imagination" (2T 470.1). * **Physical Consequences:** White warned of severe physical repercussions, stating, "The practice of secret habits surely destroys the vital forces of the system" (SA 74.2). She linked it to weakness, exhaustion, and susceptibility to diseases like consumption, explaining that the "drain upon the system is great" (2T 470.1). * **Spiritual and Mental Impact:** According to her writings, this habit hinders spiritual growth. She stated, "When persons are addicted to the habit of self-abuse, it is impossible to arouse their moral sensibilities to appreciate eternal things or to delight in spiritual exercises" (2T 470.1). She also noted that it weakens moral and intellectual faculties while strengthening "animal passions" (2T 470.1). * **A Call to Purity:** She urged individuals, especially the young, to live a life controlled by principle rather than passion. "Every Christian will have to learn to restrain his passions and be controlled by principle. Unless he does this he is unworthy of the Christian name" (2T 347.1). * **Hope and Recovery:** Despite the strong warnings, she offered a path to victory through divine help. She encouraged individuals to repent and seek God's strength, writing, "If they in humility entreat God for purity of thought, and a refined and sanctified imagination, he will hear them, and grant their petitions" (ApM 22.2). She assured that "a merciful God will accept true heart repentance, and will bless their endeavors to cleanse themselves from all filthiness of the flesh and spirit" (ApM 22.2).
