Yes, today is Corpus Christi, Bóże Ciało in Polish (the Body of Christ) -- we just have had a number of processions and prayers to Christ for Poland, and the world. It was quite moving, the entire country is shut and many are praying.
Do remember that there are orthodox Lutherans beyond the LCMS and WELS in the Society of the Holy Trinity.
I apologize if I missed them out -- thank you for the link
1. O Lord, we praise Thee, bless Thee, and adore Thee,
In thanksgiving bow before Thee.
Thou with Thy body and Thy blood didst nourish
Our weak souls that they may flouish:
O Lord, have mercy!
May Thy body, Lord, born of Mary,
That our sins and sorrows did carry,
And Thy blood for us plead
In all trial, fear, and need:
O Lord, have mercy!
2. Thy holy body into death was given,
Life to win for us in heaven.
No greater love than this to Thee could bind us;
May this feast thereof remind us!
O Lord, have mercy!
Lord, Thy kindness did so constrain Thee
That Thy blood should bless and sustain me.
All our debt Thou hast paid;
Peace with God once more is made:
O Lord, have mercy.
3. May God bestow on us His grace and favor
To please Him with our behavior
And live as brethren here in love and union
Nor repent this blest Communion!
O Lord, have mercy!
Let not Thy good Spirit forsake us;
Grant that heavenly-minded He make us;
Give Thy Church, Lord, to see
Days of peace and unity:
O Lord, have mercy!
