This survey conducted a snowball-sampling online survey of 290 current pastors’ wives in Taiwan. It considers “Ministry Calling,” “Marriage Satisfaction” and “Family Life Satisfaction” as independent variables, and attempts to justify that these factors correlate with the Pastor's Wife's Happiness in her Everyday Life and in her Ministry. In the past, research on pastors’ wives in Taiwan was limited to a single denomination and qualitative study. This study seeks to supplement "cross-denominational" and "quantitative" elements as a breakthrough for Taiwan's current research. It is hoped that through the results of this study, the Christian Church in Taiwan will be more aware of the current situation of the pastors’ wives and start to value the importance of Social Science research. The results of this study found that while controlling the "age", "years of marriage", "years of being a pastor's wife", "time spent ministering per week", "having received theological training or not" and "population of the church," the “happiness in everyday life” and “happiness in ministry” are positively correlated with “Ministry Calling,” “Marriage Satisfaction,” and “Family Life Satisfaction.” In addition, the results of this study found out that the "church population" is also a significant predictor, although its influence is less than that of the independent variables described above.
