The phrase you mentioned, "let man not separate what God has put together," is derived from a biblical passage found in the New Testament of the Christian Bible, specifically in the books of Matthew and Mark. It is often referenced in the context of marriage. Let's take a closer look at the context and meaning of this verse:
Matthew 19:4-6 (New International Version) states:
"4 'Haven’t you read,' he replied, 'that at the beginning the Creator 'made them male and female,' 5 and said, 'For this reason, a man will leave his father and mother and be united to his wife, and the two will become one flesh'? 6 So they are no longer two, but one flesh. Therefore, what God has joined together, let no one separate.'"
Mark 10:6-9 (New International Version) similarly says:
"6 'But at the beginning of creation God 'made them male and female.' 7 'For this reason, a man will leave his father and mother and be united to his wife, 8 and the two will become one flesh.' So they are no longer two, but one flesh. 9 Therefore what God has joined together, let no one separate."
In these passages, Jesus is responding to questions from the Pharisees about divorce. He cites the Genesis account of creation (Genesis 1:27 and Genesis 2:24) to emphasize the sacred nature of marriage. The phrase "what God has joined together, let no one separate" conveys the idea that marriage is a divine institution, and it is meant to be a lifelong union between a man and a woman.
In the Christian context, these verses are often interpreted to mean that marriage is not merely a human contract but a covenant established and blessed by God. Therefore, according to this interpretation, divorce should not be taken lightly, and couples should strive to maintain their commitment to each other and work through challenges together.
It's important to note that different Christian denominations may interpret and apply these verses in various ways. Some may emphasize the sanctity of marriage and discourage divorce altogether, while others may acknowledge the reality of human brokenness and offer more nuanced teachings on divorce and remarriage.
As with any biblical teaching, understanding and interpretation may vary among individuals and religious communities. For those seeking guidance on marriage and relationships from a Christian perspective, it's essential to consult with trusted spiritual leaders or study relevant biblical resources within the context of their faith tradition.
