Enemies to righteousness are enemies to Christ. This precludes those from the blessedness who suffer justly, and are evil spoken of truly for their real crimes; let such be ashamed and confounded, it is part of their punishment; it is not the suffering, but the cause, that makes the martyr. Those suffer for righteousness’ sake, who suffer because they will not sin against their consciences, and who suffer for doing that which is good. Whatever pretence persecutors have, it is the power of godliness that they have an enmity to; it is really Christ and his righteousness that are maligned, hated, and persecuted. – Matthew Henry, Commentary on Matthew 5
