Our Lord Jesus Christ Himself said that we would be hated:
7The world hates the Holy Catholic Church for the same reason it hated Christ: It teaches by the Spirit of God.
"If the world hates you, realize that it hated me first.
If you belonged to the world, the world would love its own; but because you do not belong to the world, and I have chosen you out of the world, the world hates you. (John 15:18-19)
And I will ask the Father, and he will give you another Advocate 8 to be with you always, the Spirit of truth, 9 which the world cannot accept, because it neither sees nor knows it. But you know it, because it remains with you, and will be in you. I will not leave you orphans; I will come to you. 10 (John 14:16-18)Protestantism, of course, affirms that Christ DID leave us orphans - that's why they believe the preposterous blasphemy that God abandoned His own Church for some 1,000(+) years and let it fall into apostasy and heresy.
Notice how anti-Catholic attacks parallel the attacks upon Christ by looking at the forgiveness of sin.
Christ's enemies called him a blasphemer for forgiving sins:
"He commits blasphemy! Who can forgive sins except God alone?" (Mark 2:1-12; Matt 9:1-8)Christ gave his Church the same power:
14The world has shifted its accusations and attacks from Christ Himself to his Church:
(Jesus) said to them again, "Peace be with you. As the Father has sent me, so I send you." 15 And when he had said this, he breathed on them and said to them, "Receive the holy Spirit. 16 Whose sins you forgive are forgiven them, and whose sins you retain are retained." (John 20:21-23)
"Who can forgive sins but God?"
Just as Christ predicted.
