This study is an exploration of the entire process of promoting priestly vocations in the Diocese of Xuan Loc, Vietnam. Mainly, it aims 1) to identify the most important elements in the promotion of priesthood in order that formators and vocation promoters may apply them appropriately in Vietnam, and 2) to develop a process for guiding young men toward discerning whether they have this personal vocation from God and responding to their vocation maturely and freely. The tesina focuses on the reality of vocations in the present context of Vietnam and is based on Church teachings, particularly on the Ratio Institutionis Sacerdotalis of the CBCV, which presents the entire process of promoting priestly vocations, from the embryonic, the premature, to the mature stages. The writer expands the three-fold process of nourishment, orientation, and cultivation, describing each phase and emphasizing their characteristics. Together with prayer, these key elements form the very heart of the promotion of all aspects and stages of the priestly vocation.
