Academic commentaries focus on the detailed aspects of a passage such as context, literary meaning, translations, sources, etc. Their general approach is critical with attentive to detail. They may or may not be theological or include practical comments for application in life (devotional).
Lay commentaries are similar but are not as critical. Their focus is on how to apply a particular passage for spiritual formation. They emphasize application and personal impact.
