Sue Stephenson (Write Back, January 1) misunderstands marriage if she thinks it means "one person possessing another".
The legal definition of marriage is "the voluntary union for life of one man and one woman to the exclusion of all others".
It is something which has been tried and tested down the generations and found to be the best way for an ordered society.
To try to change the meaning to include same-sex couples is impossible; there cannot be two husbands or two wives if the human race is to continue.
Civil partnerships give same-sex couples all the rights associated with marriage legally, so why do some of them want what is biologically impossible?
As the new Church of Ireland Archbishop of Armagh, the Most Revd Dr Richard Clarke, has said, equivalence and equality are not the same thing.
