The conjugality established by the number of legal marriages performed has decreased in recent years, but also suffers the onslaught of divorce that has risen in alarming numbers. This situation affects parenthood, and especially among Christians it is noticeable in the desertion of children from the faith of their parents. Likewise, there is a decrease in the Christian commitment of active parishioners in Christian churches. The objective of this research was to determine the relationship between Christian commitment, conjugality and parenthood of married Adventist parishioners. For this purpose, a non-experimental, cross-sectional research design was carried out on a sample of 519 Adventist parishioners in the province of Callao, the northern area of the province of Lima and the province of Santa. The results confirmed that there is a strong and direct correlation between Christian commitment and conjugality (Spearman's Rho coefficient of 0.586) and Christian commitment and parenthood (Spearman's Rho of 0.578). It is concluded that if Christian commitment improves, conjugality and parenthood also improve.
