The Doctrine Of The Trinity In Southern African Seventh-Day Adventism: A Historical-Theological Study, 1887-1974, Grant Lottering

Master's Theses

The Topic

The doctrine of the Trinity in the history of the Seventh-day Adventist Church has often been viewed with suspicion, largely because many early Adventist pioneers expressed seemingly anti-Trinitarian sentiments. However, a review of Seventh-day Adventist publications reveals that early Adventists actually rejected Modalism, a misunderstood variation of Trinitarianism, rather than the biblical concept of the Trinity. When Seventh-day Adventist missionaries arrived in Africa in 1887, the earliest converts had a Dutch Reformed background and were already Trinitarian. Seventh-day Adventists found that their understanding of the Trinity aligned with these converts’ beliefs, and thus, they never needed to correct …

Analyzing The Safety Effects Of Edge Lane Roads For Motor Vehicle Users, John Yang

Master's Theses

This thesis builds upon a prior study that analyzed the safety effects of Edge Lane Roads (ELRs) within the U.S. context, addressing gaps related to collision, traffic volume, and speed data.
