This research aims to explain and describe the Batak Community's views on Christian marriage without the existence of Toba Batak traditional ceremonies at the HKBP Church, Denpasar City. The method required for this research is a descriptive qualitative approach.

The subjects of this research were married Toba Batak people, young people who were about to get married, pastors and elders of the HKBP Church in Denpasar City. The results of this research are that couples who carry out a Christian wedding ceremony but do not carry out the Toba Batak traditional wedding ceremony can be caused by economic factors, education, not getting the blessing or approval of both parents of the couple's family, differences in beliefs and cultural values. as well as ethics. Several couples from the Toba Batak community of the HKBP Church in Denpasar City were mostly due to spending a lot on Toba Batak traditional peak party activities, specifically dowry money. Apart from that, there are thoughts of today's young people who are of the opinion that marriage according to Christian beliefs is already valid or official through a marriage blessing in the Church, but according to tradition, the couple still has debts that must be paid off immediately in order to be recognized and prayed for as having entered into a legal marriage. This occurs because of the transition to modernization which results in a shift in a socio-cultural structure such as kinship, traditional philosophy, roles or functions and etc.
