How can "confession" mean praise?

Question

I was looking at a short summary of Augustine's Confessions, and came across a statement by the translator that though the word "confession" can mean acknowledgement of sin, it can also be a statement of praise. Elsewhere, in religious writings, I also see it apparently meaning giving thanks, making a vow, etc. Yet the dictionaries I looked at, don't have these meanings for confession. They only mention confessing to one's sins or crimes or something that one finds shameful or embarrassing. Confession's etymology apparently goes to "confiteri" which simply means to acknowledge.

Appreciate any help.

LATER EDIT: I'll quote it from the book: "The very title itself can be read two ways: Of confession as praise, as well as confession as acknowledgement of faults." That's from the introduction, nothing more is said of that.

Answer 1

Oxford Dictionary gives one meaning of confession as:

confession of faith
A statement setting out essential religious doctrine:
a Protestant confession of faith

Chambers Dictionary specifies one of the meanings of confession as

a declaration of one's religious faith or principles • a confession of faith.

This website refers to:

a "Faith Confession for Praise and Worship"

and states:

"Read the following confession several times each day to give praise and worship …"

Your question refers to "a statement by the translator that … the word 'confession' … can … be a statement of praise." and your quotation from the book actually states:

"The very title itself can be read two ways: Of confession as praise, as well as confession as acknowledgement of faults."

Note that the quotation from the book did not actually state that confession means praise — rather that confession [of faith] can be a "statement of praise". That seems to me to be supported by the stated dictionary definitions and the usage examples given above.
