Why is inculturation in Catholic theology difficult to operationalize?

This article attempts to explain sociologically why the Catholic Church's popular theological concept of inculturation is difficult to operationalize or provide empirical indicators in order to make it more observable and measurable for social scientists, missionaries, and inculturation practitioners. Using some secondary data and peer-reviewed literature, it explores how the following major hurdles inhibit the clear conceptualization and operationalization of inculturation projects, namely: the (1) lack of unified definition in the Church for culture, (2) plurality of the meaning of inculturation, (3) ambiguity of the extent of the cultural change in inculturation that results in unsettled levels and units of analysis in measuring it, as well as (4) lack of social science training and expertise of Catholic theologians, clerics, and missiologists, leading to the neglect of empirical studies that operationalize inculturation in the mainstream research. This study recommends intensified social science training for missionaries and clerics in the Catholic Church and active dialogue between inculturationists and social scientists to enhance the empirical dimension of inculturation in research and literature.
