These blessings are performed in an official capacity by the Church, but it's also a nice family custom, one that literally "brings home" the importance of formally asking God's intercession in our daily lives, for the success of our endeavors and the safety of our homes. We all felt very safe here on our little farm when we had finished!
The Blessing of Crosses to be Placed in Fields and Vineyards
(Usually said on May 3rd, on the Feast of the Finding of the Holy Cross ~ But we decided to add it to our Greater Litany blessings. We placed four crosses made from pickets in the four corners of our "close in" acreage.)
Almighty, everlasting God, Father of goodness and consolation, in virtue of the bitter suffering of Thy Sole-Begotten Son, our Lord, Jesus Christ, endured for us sinners on the wood of the Cross, bless these crosses which Thy Faithful will erect in their vineyards, fields, and gardens. Protect the land where they are placed from hail, tornado, storm, and every assault of the enemy, so that their fruits ripened to the harvest may be gathered to Thy honor by those who place their hope in the holy Cross of thy Son, our Lord, Jesus Christ, Who livest and reigneth with Thee eternally.
Bless this sprouting seed, strengthen it in the gentle movement of soft winds, refresh it with the dew of heaven, and let it grow to full maturity for the good of body and soul.
