Relationships, Marriage, & Family Life in Vatican City
Most of the citizens and residents of Vatican City are clergy and according to the Catholic Church, clergy (other than deacons) cannot marry as they take a vow of chastity. Likewise, nuns, religious sisters, and monks may not marry either. Because of this vow, and due to the fact that many citizens of Vatican City are clergy or religious sisters, marriage and family life in Vatican City are fairly unnoticeable and nearly non-existent. Additionally, to become a member of the Swiss Guard a man must be single.
Because of the Catholic Church and the citizenship of Vatican City, dating is essentially absent as are marriage and children. Of course, many of the people that work in Vatican City, but live in Rome are married and have families. Many of the Swiss Guard members also move on from their assignment in the Vatican to marry and start families, but not until after they have left.
