The U.S. Bishops are in the process of approving changes to the English language liturgy of the Holy Mass for use in all English speaking countries around the world. They have set up a very easy to understand table on their web page.
Here are some of the changes to the major prayers of the Mass: You can find their web page in table form here.
The Missale Romanum (the Roman Missal), the ritual text for the celebration of the Mass, was first promulgated by Pope Paul VI in 1970 as the definitive text of the reformed liturgy of the Second Vatican Council. A second edition followed in 1975.
Pope John Paul II issued a revised version of the Missale Romanum during the Jubilee Year 2000. The English translation of the revised Roman Missal is nearing completion, and the Bishops of the United States will vote on the final sections of the text this November. Among other things, the revised edition of the Missale Romanum contains prayers for the observances of recently canonized saints, additional prefaces for the Eucharistic Prayers, additional Votive Masses and Masses and Prayers for Various Needs and Intentions, and some updated and revised rubrics (instructions) for the celebration of the Mass. The English translation of the Roman Missal will also include updated translations of existing prayers, including some of the well–known responses and acclamations of the people.
Priest: The Lord be with you.
People: And with your spirit.
I confess to almighty God
and to you, my brothers and sisters,
that I have greatly sinned
in my thoughts and in my words,
in what I have done
and in what I have failed to do,
through my fault, through my fault,
through my most grievous fault;
therefore I ask blessed Mary ever-Virgin,
all the Angels and Saints,
and you, my brothers and sisters,
to pray for me to the Lord our God.
Glory to God in the highest,
and on earth peace to people of good will. We praise you, we bless you, we adore you, we glorify you,
we give you thanks for your great glory,
O God, almighty Father.
Lord Jesus Christ, Only Begotten Son,
Lord God, Lamb of God,
Son of the Father,
you take away the sins of the world,
have mercy on us;
you take away the sins of the world, receive our prayer;
you are seated at the right hand of the Father, have mercy on us.
For you alone are the Holy One,
you alone are the Lord,
you alone are the Most High, Jesus Christ, with the Holy Spirit,
in the glory of God the Father. Amen.
I believe in one God,
the Father almighty,
maker of heaven and earth,
of all things visible and invisible.
And in one Lord Jesus Christ,
the Only Begotten Son of God,
born of the Father before all ages.
God from God, Light from Light,
true God from true God,
begotten, not made,
consubstantial with the Father;
through him all things were made.
For us men and for our salvation
he came down from heaven,
and by the Holy Spirit
was incarnate of the Virgin Mary,
and became man.
For our sake
he was crucified under Pontius Pilate,
he suffered death and was buried,
and rose again on the third day
in accordance with the Scriptures.
He ascended into heaven and is seated
at the right hand of the Father.
He will come again in glory
to judge the living and the dead
and his kingdom will have no end.
And in the Holy Spirit, the Lord,
the giver of life, who proceeds
from the Father and the Son,
who with the Father and the Son
is adored and glorified,
who has spoken through the prophets.
And one, holy, catholic
and apostolic Church.
I confess one baptism
for the forgiveness of sins
and I look forward to the resurrection
of the dead
and the life of the world to come. Amen.
[For the life of me, I can't figure out why the translators like the phrase "for us men." The French use "por nous" which means simply "for us" and the Germans use "fuer uns Menschen" which means "for mankind" or "for we humans", not man. I'm sure there are examples in many other languages].
I believe in God, the Father almighty,
Creator of heaven and earth,
and in Jesus Christ, his only Son,
who was conceived
by the Holy Spirit,
born of the Virgin Mary,
suffered under Pontius Pilate,
was crucified, died and was buried;
he descended into hell;
on the third day he rose again
from the dead;
he ascended into heaven,
and is seated at the right hand
of God the Father almighty;
from there he will come to judge
the living and the dead.
I believe in the Holy Spirit,
the holy catholic Church,
the communion of saints,
the forgiveness of sins,
the resurrection of the body,
and life everlasting. Amen.
Agnus Dei and Lord I am not worthy
Priest: Behold the Lamb of God,
behold him who takes away
the sins of the world.
Blessed are those called
to the supper of the Lamb.
that you should enter under my roof,
but only say the word
and my soul shall be healed.
