I recently read a book that described the type of culture which was present during the time of Jesus and the Apostles. This author makes the case that back then, an individual's relationship with siblings took precedence over one's relationship with one's spouse. He points to different passages of Scripture which exhort for believers to live as a surrogate family. This entails sharing possessions, time, and genuine brotherly love with other followers of Christ.
The author also mentions that life's biggest decisions (e.g., marriage, vocation, etc.) were meant to be made within the context of community. This means receiving input from other individuals who one knows well and whom is well known by this community. The individual's community can offer insight pertaining to one's strengths, weaknesses, talents, abilities, etc. The point being these decisions were not meant to be made in isolation.
