Many church people think that the last verse of the hymn text "Awake, my Soul, and with the Sun, written by Thomas Ken in the 17th century, IS "The Doxology." Here is that text:
Praise God, from Whom all blessings flow;
Praise Him, all creatures here below;
Praise Him above, ye heavenly host;
Praise Father, Son, and Holy Ghost.
But there are many other doxologies, any one of which might be a legitimate candidate for being called "The Doxology."
For example, the last bit of the Lord's Prayer is its doxology:
"For Thine is the Kingdom, and the power, and the glory, for ever. Amen" (Matthew 6:13)
For another example, in Roman Catholic prayer, the following is considered "The Doxology":
Gloria Patri, et Filio, et Spiritui Sancto. Sicut erat in principio, et nunc, et semper, et in saecula saeculorum. Amen.
... or in English (which presumably God translates back into Latin in His head) ...
Glory be to the Father, and to the Son, and to the Holy Spirit. As it was in the beginning, is now, and ever shall be, world without end. Amen.
The Greek Orthodox use the term to refer to yet another hymn altogether.
It rarely makes sense to say/write "The Doxology" without explaining which one is in mind.
