Guarding the flock IS loving the flock

One aspect of the demands of love is the guarding of the sheep from the danger of error. Heresy has a siren's voice and the devil uses its sweet sound to lure the Church away from a sincere and pure devotion to Christ. A false Christ, who can never be the proper object of our affections, can never make the new Eve fruitful in the world (2 Cor. 11:24). That is why heresy is destructive, it cannot produce spiritual fruit, there is no power in it to bring a new creation.

Pastors, elders, the demands of love require you to protect the Church from heresies, even when people will call you unloving for criticizing the views of others. To do so, in our age, may well be called unloving, for our age has confused tolerance with love, but the insult is ill judged.

Protecting the Church from error is a loving act, and, therefore, it must be done with the appropriate affections. We are not to love a fight, we are to fight because we are motivated by love.
