Ordinances for the dead is a false doctrine of the Church. Baptisms for the Dead was only given for our benefit, so that we can remember our own baptisms.
Endowments and sealings for the Dead are not something you should be concerned with.
Joseph Smith Junior made it perfectly clear, as did his successors, that baptism for the dead was for the benefit of the dead, who could not obtain "salvation" without being baptized either in person or by proxy. It is the Sacrament that is given that we
may eat in remembrance of the body of thy Son, and witness unto thee, O God, the Eternal Father, that [we] are willing to take upon [us] the name of thy Son, and always remember him, and keep his commandments which he hath given [us], that [we] may always have his Spirit to be with [us].
in remembrance of the blood of thy Son, which was shed for them; that they may witness unto thee, O God, the Eternal Father, that they do always remember him, that they may have his Spirit to be with them.
We have been taught from Primary on, that the Sacrament is taken as a remembrance and a renewal of our baptism covenants.
New prophets and patriarchs come along from time to time and "revise" the Restored Gospel, more often damaging it then improving it. In the end, however, they all seem to fall short of a genuinely Divine Standard.
Klaus1787 was not concerned with endowments and sealings for the dead. He was concerned about the pretensions and contradictions of those Mormon leaders who claimed to be doing ordinances for the signers of The Declaration of Independence, some U.S. Presidents and foreign statesmen and famous authors, scientists, etc., but apparently not the members of Congress under the Articles of Confederation, the members of the Constitutional Convention, and other statesmen and patriots.
