The traditional Hebrew mezuzah is a parchment with the Shema, verses from Deuteronomy, written in Hebrew. The parchment is prepared by a qualified "sofer," who has many years of training. The verses are written in indelible black ink with a special quill pen. The parchment is then placed inside the case. The mezuzah is affixed on the right side of the door (from the point of view of a person entering the room), in the upper third of the doorpost. In some Hebrew traditions the mezuzah is tilted slightly pointing into the home. Mezuzahs have many decorative designs, but each will always have the Hebrew character Shin, which means Shaddai - Almighty God.
The scripture in the new mezuzah has been updated to Jesus' Great Commandment where he first recites the Shema, "Hear O Israel, the Lord our God is one Lord..." and finishes with "... Thou shalt love thy neighbor as thyself." Here the words are not hidden as in the Hebrew mezuzah.
The design is transparent reminding us that Jesus cleared the way to God. And while the Shin is still on the mezuzah, the cross reminds us of the gift He gave us through Christ. The oval shape symbolizes the never ending, eternal love of Christ.
The colors of this mezuzah are borrowed from traditional Christian symbolism:
Gold represents the wisdom and glory of God
Silver is the purity of Jesus
Purple is for royalty
Green represents new life in Christ
Blue is a symbol of the Holy Spirit, truth and heaven
Red reminds us of the blood of Jesus
