Catholicism, Protestantism, Orthodoxy: all have majestic saints which means all will have great sinners. And believe it or not, we have one Master in Jesus Christ. Period.
True, a papist will chide the sola scriptura adherent for lack of tradition whereas the latter chides the former’s lack of scriptural literacy among the laity. The Orthodox will look at these two Western strains and harp at them as products of a vain schism lasting nearly a millennium, seeing itself as a divine tradition of the East. Likewise, the West shifts blame of this same schism back to the Orthodox. Every tradition is guilty of doubting the other’s faith in Christ because of its ecclesiology.
But let’s face facts: the world is encroaching on Christians everywhere. With the advent of ISIS, all are marked as a Nazarene regardless of geographical location. All are marked for slaughter. We’re targets at school, in the workplace, and by governments that operate in the name of “democracy”. Christendom is the no longer the prevailing voice of civilization, because it is an ultimate subscription to the Kingship of Jesus the Christ, which is always incompatible with the many faces of Caesar.
We have to hang together lest we hang separately. He who is not against you is for you. He who is not against Christ is for Christ. Our differences remain and are important to the practice of our faith, sure. But let us hash out confessions and hierarchical scruples elsewhere in peace.
Today is a time of war. As Tertullian noted, the blood of the martyrs is the seed of the Church. This scarlet seed is irrigated by Catholic, Protestant, and Orthodox alike. Why? Because He who sanctifies by His blood and those who are sanctified by Him have God as their Father.
We are the children of God, the Father of Lights, and not of the Evil One who dwells in darkness. Let us fight off the black horde together. Let us by our deeds of love prompted by the Mercy given us, muster strength to charge against the blind wickedness snuffing out Truth, Goodness, and Beauty. Let the citadel of the City of God be ablaze to guide the nations once more to the Lamb who is the Light.
