Does the Catholic Church say which is the correct rendering in english of The Glory Be (The Doxology)? This is one rendering of The Glory Be:


  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.


And this is another:


  Glory be to the Father, and to the son, and to the Holy Spirit. As it
  was in the beginning, is now, and will be forever. Amen.


Does the Catholic Church say which of these is the correct rendering in english of The Glory Be (The Doxology)? If none is, what is the correct rendering in english of The Glory Be (The Doxology) according to the Catholic Church?



This is what got me thinking, that the Mass in English has a New Translation.
An Official version is available On Line from the Vatican

This link takes you to the compendium of the catechism of the Catholic Church which is hosted at the Vatican's web page.  In Appendix A, Common Prayers, the Gloria Patri is rendered with Latin next to English.  

English:  


  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.


Latin


  Glória Patri et Fílio et Spirítui Sancto. Sicut erat in princípio, et nunc et semper et in sæ´cula sæculórum. Amen.


Given the source, it's about as official as one can ask for. 

Note:  


In this prayer's case, unlike the Hail Holy Queen, Te Deum, Magnificat, and Benedictus prayers, the Vatican did not break it into "UK English" and "US English" versions.  This indicates that they went to some trouble to render it to the best of their ability. 
Given the 2011 changes to the Liturgy, in English, to get closer to literal translations from the Latin into the English, there may be a change in time (the RCC moves slowly, when it moves at all) to render that prayer more literally.  Since the date for the Compendium seems to be the year 2005, there may be an update coming.  Or not.
