A voice from the past suggests they are not:
"But Catholic doctrine tells us that the primary duty of charity does not lie in the toleration of false ideas, however sincere they may be, nor in the theoretical or practical indifference towards the errors and vices in which we see our brethren plunged, but in the zeal for their intellectual and moral improvement as well as for their material well-being. Catholic doctrine further tells us that love for our neighbor flows from our love for God, Who is Father to all, and goal of the whole human family; and in Jesus Christ whose members we are, to the point that in doing good to others we are doing good to Jesus Christ Himself. Any other kind of love is sheer illusion, sterile and fleeting.
Indeed, we have the human experience of pagan and secular societies of ages past to show that concern for common interests or affinities of nature weigh very little against the passions and wild desires of the heart. No, Venerable Brethren, there is no genuine fraternity outside Christian charity. Through the love of God and His Son Jesus Christ Our Saviour, Christian charity embraces all men, comforts all, and leads all to the same faith and same heavenly happiness.
By separating fraternity from Christian charity thus understood, Democracy, far from being a progress, would mean a disastrous step backwards for civilization. If, as We desire with all Our heart, the highest possible peak of well being for society and its members is to be attained through fraternity or, as it is also called, universal solidarity, all minds must be united in the knowledge of Truth, all wills united in morality, and all hearts in the love of God and His Son Jesus Christ. But this union is attainable only by Catholic charity, and that is why Catholic charity alone can lead the people in the march of progress towards the ideal civilization. "
