✅ Acknowledge and confess both mean to admit that you’ve done something wrong.
✅ Confess is the best verb for a formal or semi-formal admission of wrongdoing (to confess your sins).
✅ Acknowledge implies reluctance in the statement of wrongdoing or of something previously denied (I acknowledge that my behavior was wrong; She acknowledged that she had broken the cup).
✅ Acknowledge usually suggests fault for things that, while possibly wrong, aren’t criminal (acknowledge a gap in your understanding). Confess can be used for crimes (confess to a robbery), as well as other wrongdoings, faults, or shortcomings that can imply embarrassment (He confessed that he had been eavesdropping).
