Although you can be a temple of the Holy Spirit by yourself, you cannot be Church by yourself. So, as a Catholic in Eswatini, Botswana and South Africa, you belong to a parish, then possibly a deanary, then a Diocese or Vicariate, then SACBC, the IMBISA then SECAM as part of your Catholic Family in Africa in the bigger family of the One, Holy, Catholic, and Apostolic Church.
