Lion of the Tribe of Judah for the Altar?

The picture above was taken on 2 November (Altar cards down at that moment). I’m mulling over creating something for the front of the altar, with inspiration taken from the coat of arms of the Pontifical Biblical Institute:

Just the bits in the middle:

• The Sacred Heart of Jesus with the crown of thorns.
• That Heart topped by the two beams of the cross each of which count as one of the rays of Light shining from the Sacred Heart.
• The rays of Light come from the Lumen gentium, the Light of the Nations, Christ Jesus, shining through the twelve tribes of Israel and the twelve Apostles (Judas replaced altogether). There are eleven rays of Light otherwise. The two cross beams fill up the count.
• The Alpha and Omega, as Scripture says, Jesus, the First and the Last, the Almighty.
• The Lion of the Tribe of Judah, the Messiah, Jesus, presented as a winged Cherub, for it is YHWH Elohim Incarnate who provides the flame of charity, the grace, by which sanctification comes about.
• The Scriptures of the words inspired by the Holy Spirit about The One Eternal and now Incarnate Word of our Heavenly Father.
• The Flaming Sword of Division: Hebrews 4:12-13 “For the word of God is living and active. Sharper than any double-edged sword, it pierces even to dividing soul and spirit, joints and marrow. It judges the thoughts and intentions of the heart. Nothing in all creation is hidden from God’s sight; everything is uncovered and exposed before the eyes of Him to whom we must give account.”
• The Star of David, in expectation of the seventh point of fulfilment, of perfection, which is the Incarnation of the Son of David, the Son of God: “The Lord said to my Lord…” (see Matthew 22:44), with Jesus depicted just above that Star of David.

Just mulling it over. What think ye?
