I don't disagree with you Alex. Wesley, Luther (A Mighty Fortress is Our God), Haugen, Haas ... and a bunch of other hymns as well. It is shameful to have clearly Protestant hymns (with Protestant theology included) used in the Catholic Mass.
While I agree that there are some hymns that should be kept out (e.g. "A Mighty Fortress is Our God", which was sung while the Lutherans slaughtered Catholic priests and nuns) there are MANY good hymns that are compatible with Catholic theology, including some great ones about the Virgin Mary. If we were to only use hymns written by Catholics we would have the English Roman Catholic "Westminster Hymnal" of the 1920s--a slim book indeed.
Here are two Anglicans hymns that stand out:
(This is a paraphrase of the Anima Christi
)Soul of Jesus, make me whole,
Meek and contrite make my soul;
Thou most stainless Soul divine,
Cleanse this sordid soul of mine,
Hallow this my contrite heart,
Purify my every part;
Soul of Jesus, hallow me,
Save me, body of my Lord,
Save a sinner, vile, abhorred;
Sacred body, wan and worn,
Bruised and mangled, scourged and torn,
Pierc�d hands and feet and side,
Rent, insulted, crucified:
Save me: to the cross I flee,
Blood of Jesus, stream of life,
Sacred stream with blessings rife,
From the broken body shed
On the cross, that altar dread;
Giv�n to be our drink divine,
Fill my heart and make it thine;
Blood of Christ, my succor be,
Holy water, stream that poured
From Thy riven side, O Lord,
Wash Thou me without, within,
Cleanse me from the taint of sin,
Till my soul is clean and white,
Bathed and purified and bright
As a ransomed soul should be,
Jesus, by the wondrous power
Of Thine awful passion hour,
By the unimagined woe
Mortal man may never know;
By the curse upon Thee laid,
By the ransom Thou hast paid,
By Thy passion comfort me,
Jesus, by Thy bitter death,
By Thy last expiring breath,
Give me the eternal life,
Purchased by that mortal strife;
Thou didst suffer death that I
Might not die eternally;
By Thy dying quicken me,
Miserere, let me be
Never parted, Lord, from Thee;
Guard me from my ruthless foe,
Save me from eternal woe;
When the hour of death is near,
And my spirit faints for fear,
Call me with Thy voice of love,
Place me near to Thee above,
With Thine angel host to raise
An undying song of praise,
Here's another one related to Good Friday:My song is love unknown,
My Savior�s love to me;
Love to the loveless shown,
That they might lovely be.
O who am I, that for my sake
My Lord should take, frail flesh and die?
He came from His blest throne
Salvation to bestow;
But men made strange, and none
The longed for Christ would know:
But O! my Friend, my Friend indeed,
Who at my need His life did spend.
Sometimes they strew His way,
And His sweet praises sing;
Resounding all the day
Hosannas to their King:
Then �Crucify!� is all their breath,
And for His death they thirst and cry.
Why, what hath my Lord done?
What makes this rage and spite?
He made the lame to run,
He gave the blind their sight,
Sweet injuries! Yet they at these
Themselves displease, and �gainst Him rise.
They rise and needs will have
My dear Lord made away;
A murderer they saved,
The Prince of life they slay,
Yet cheerful He to suffering goes,
That He His foes from thence might free.
In life, no house, no home
My Lord on earth might have;
In death no friendly tomb
But what a stranger gave.
What may I say? Heav�n was His home;
But mine the tomb wherein He lay.
Here might I stay and sing,
No story so divine;
Never was love, dear King!
Never was grief like Thine.
This is my Friend, in Whose sweet praise
I all my days could gladly spend.
