Ticonius — on Rev 6:12 (COMMENTARY ON THE APOCALYPSE 6:12)

“In the sixth seal we recognize the sixth age of the world. Toward the conclusion of this age the last persecution will come, and it says that the vehement shock of this persecution will shake the whole world like an earthquake. The sun and the moon are Christ and the church. The sun is said to become black, because many will be terrified at the last persecution and will deny them. It says, "Even if our gospel is veiled, it is veiled to those who are perishing, for the god of this world has blinded the minds of the unbelievers, so that the brightness of the gospel of the glory of Christ, who is the image of God, might not shine." And therefore it says, "so that even the elect, if possible, are led into error." In this manner is the sun said to become black, when the power of Christ is hidden, or doctrine is obscured for a time, or defense is delayed when the impious are allowed to attack the saints. And therefore the prophet says, "Shall you leave this unnoticed, that the impious swallows the righteous?" And indeed of Christ himself we read, "Behold, this child is set for the fall and resurrection of many, and for a sign that is spoken against." In him some make progress; others, turning away from him, incur ruin. "The moon turned to blood." It is usually foretold that the church will shed more blood for Christ when the great outbreak of persecutions occurs. Therefore, this speaks of her own blood, not the blood of another as was the case with the red horse, which was described as red with another's blood.”
