solemn vow

Binding sacred pledge

A solemn vow is a serious, formal promise made with deep commitment and gravity.

The phrase emphasizes the weight of the commitment—solemnity distinguishes it from casual promises: She took a solemn vow never to speak of what she had witnessed.

In religious contexts, solemn vows are binding commitments made before God, as when entering a monastic order.
