The Bible does not specifically address the concept of a legal marriage performed without God's presence or without being solemnized before a religious congregation or community (church). The Bible's teachings on marriage primarily focus on the principles of love, commitment, faithfulness, and the union of two individuals as "one flesh."
In Christianity, marriage is often considered a sacred covenant before God, and many couples choose to have their weddings officiated by a minister or pastor within a church setting. This is done as an acknowledgment of God's role in the marriage and an expression of commitment to follow biblical principles in their union.
However, it's important to note that civil marriages, recognized by law and conducted by government officials or authorized individuals, are also considered legally valid in many societies, even if they do not involve a religious ceremony or are not performed within a church.
The Bible does emphasize the importance of honoring legal authorities and following the laws of the land (Romans 13:1-7). In this sense, civil marriage is generally seen as a legitimate form of marriage within the context of society and the law. While it may not have the same religious significance for some individuals, it still carries legal validity and responsibilities.
For Christians, the decision to have a marriage ceremony solely within a legal setting or in the presence of a religious community can be a matter of personal conviction, cultural practices, or adherence to specific denominational traditions. The most critical aspect is the commitment of the couple to each other and their willingness to uphold the biblical principles of love, respect, and faithfulness in their marriage, regardless of the setting in which the marriage is performed.
