Jesus was in the garden of Gethsemane on the night of his arrest. This garden was an olive grove and it still exists today. Gethsemane means “oil press” in Aramaic, the language spoken by Jesus.
Psalm 52:8 “But as for me, I am like a green olive tree in the house of God; I trust in the lovingkindness of God forever and ever.”
“Do you know that God gave us one more commandment, which is not recorded in Scripture? It is the commandment “love the trees.“ When you plant a tree, you plant hope, you plant peace, you plant love, and you will receive God’s blessing.” – Elder Amphilochius of Patmos
According to Met. Kallistos, the Elder frequently assigned the penance of planting a tree on the island (Patmos) for those who came to him for confession. His ministry raised up forests as well as demolished the sins of many.
