Final answer:
Itineration in Assemblies of God missions refers to the practice of missionaries traveling within their home country to obtain church support and share their experiences.
Step-by-step explanation:
The term itineration in the context of Assemblies of God missions is best defined as stateside travel by missionaries to obtain local church support. This involves missionaries traveling within their home country to raise awareness, share experiences, garner prayerful and financial support for their missions, and often involves sharing sermons, films, and displaying artifacts from the missions field. Itineration thus serves as a crucial link between the mission field and the local churches that support such endeavors.
