The Glory Be is recited in many places: At mass, after a psalm. At the end of psalms in the breviary. At the end of a decade in the rosary. And many other times:
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.
Gloria Patri et Filio et Spiritui Sancto, sicut erat in principio, et nunc, et semper, et in saecula saeculorum. Amen.
In English, there are two different ways to say this prayer, namely, the one used in the rosary, and the one used in the breviary. They are substantially the same.
