In this instance, He strongly rebuked the deliberate folly into which the spiritually blind leaders led the people: Woe unto you, you blind guides, who claim that swearing by the church means nothing, while swearing by the gold of the church carries weight. You blind guides, which is more significant: gold, or the sanctuary that sanctifies the gold? And he who swears by the altar shall not partake, but whoever swears by the gift upon it may eat. You blind guides, which holds more importance: the gift, or the altar that makes the gift sacred? As explained by the esteemed Theophylact, according to the Pharisaical teaching, anyone who swore by a golden vessel, or a sacrificial animal, and later violated their oath was obliged to offer what they swore by to the temple, as they valued the gift over the altar for personal gain. The essence of an oath is to call upon the all-knowing and ever-present God as witness to the truth. Therefore, clarifying the true purpose of an oath, the Lord stated that anyone who swears by the altar swears by it and by Him who is upon it; anyone who swears by the church swears by it and by Him who resides in it, and anyone who swears by heaven swears by the Throne of God and by the One who sits upon it.
