“Patriarchal blessings are given to worthy members of the Church by ordained patriarchs. Your patriarchal blessing declares your lineage in the house of Israel and contains personal counsel from the Lord to you.” (True to the Faith, p. 111)
This blessing identifies a person as a member of the tribe of Israel, eligible to receive all of the blessings of the Abrahamic covenant. Mormons believe that with this blessing a person receives knowledge from Heavenly Father, especially on what He expects from you. The blessing may contain promises that are associated with a person’s eternal potential. If a person remains worthy, then God will fulfill all of His promises given with this blessing.
