As Jesus said in Mark 10...
"“But at the beginning of creation God ‘made them male and female.’ ‘For this reason a man will leave his and mother and be united to his wife, and the two will become one flesh.’ So they are no longer two, but one flesh. Therefore what God has joined together, let no one separate.”
Mark 10:6-9 NIV
There has been a word that described our lifelong dedication to God as a husband and wife, but there are attempts to redefine that word so it will no longer mean this in any way.
In 1961 it became a government institution instead of being a dedication before God.
In the early 1970s it became no longer lifelong.
Now there is an attempt to withdraw the idea of being between a husband and a wife. lifelong dedication to God as a husband and wife
I am unaware of a word to describe our relationship, so I am calling it our lifelong dedication to God as a husband and wife.
