Ellen G. White does not explicitly state in Early Writings or her other published books that only those “of sufficient age and understanding” are resurrected to face judgment. Her writings emphasize that all will be judged according to their deeds, referencing both young and old, but she does not specify an age threshold or a particular level of understanding as a requirement for resurrection or judgment. The focus in her works is on character, deeds, and the investigative judgment, rather than on age or understanding as criteria.
If you would like a search in other collections, such as her manuscripts or compilations, please let me know.
