These questions address the subject of anticipatory socialization. This process occurs when people who do not belong to a particular group research and take on the values of this group, even before joining. This is done in order to increase their chances of being accepted into the group, and to make their transition easier.
In this case study, Marsha wants to join a new church as a pastor. Marsha has researched several churches and has learned about their values, the role of the pastor in each one and the internal culture they display. All of these actions represent different aspects of the anticipatory socialization process.
It is also possible for the churches to engage in this process. For example, the churches might research pastors that they are interested in, and try to learn about these people's values or past behaviours. This would allow them to find people that would best fit the values of the church in question.
