Many Protestants make straw man accusations against Catholics and the CC. Those Protestants are very angry at the CC and they call Catholics fools for blindly following the church.

Mathew 5 talks about their behavior. "22 But I say to you that whoever is angry with his brother without a cause shall be in danger of the judgment. And whoever says to his brother, 'Raca!' shall be in danger of the council. But whoever says, 'You fool!' shall be in danger of hell fire.

Romans 16: 17 Now I urge you, brethren, note those who cause divisions and offenses, contrary to the doctrine which you learned, and avoid them. 18 For those who are such do not serve our Lord Jesus Christ, but their own belly, and by smooth words and flattering speech deceive the hearts of the simple. 19 For your obedience has become known to all. Therefore I am glad on your behalf; but I want you to be wise in what is good, and simple concerning evil.

Men cannot save other men? Paul says: To the weak I became weak, that I might win the weak; I have become all things to all men, so that I may by all means save some. (1 Cor 9:22)

Are we assured our salvation? Paul says: I discipline my body and make it my slave, so that, after I have preached to others, I myself will not be disqualified for the prize. (1 Cor 9:27)

Many Protestants say Christ paid for our sins and God will not punish us for them but Numbers 5:5-10 says otherwise:
5 The LORD said to Moses, 6 "Say to the Israelites: 'Any man or woman who wrongs another in any way and so is unfaithful to the LORD is guilty 7 and must confess the sin they have committed. They must make full restitution for the wrong they have done, add a fifth of the value to it and give it all to the person they have wronged. 8 But if that person has no close relative to whom restitution can be made for the wrong, the restitution belongs to the LORD and must be given to the priest, along with the ram with which atonement is made for the wrongdoer. 9 All the sacred contributions the Israelites bring to a priest will belong to him. 10 Sacred things belong to their owners, but what they give to the priest will belong to the priest.'"

Elementary teachings are found in scripture and the CC teaches tradition as well?
"Therefore let us leave the elementary teachings of Christ and go on to maturity, not laying again the foundation of repentance from acts that lead to death, and of faith in God, instruction about baptisms, the laying on of hands, the resurrection of the dead, and eternal judgment" (Heb. 6:1--2).

Can a co-heir with Christ (Saints) NOT HEAR our prayers?
Romans 8:17 Now if we are children, then we are heirs—heirs of God and co-heirs with Christ, if indeed we share in his sufferings in order that we may also share in his glory.

Scripture alone?
John 21:25 Jesus did many other things as well. If every one of them were written down, I suppose that even the whole world would not have room for the books that would be written

2 Thessalonians 2:15 So then, brothers and sisters, stand firm and hold fast to the teachings we passed on to you, whether by word of mouth or by letter.

Should we continue to make sacrafices to God? The Catholic Mass
Hebrews 13:15 Through Jesus, therefore, let us continually offer to God a sacrifice of praise the fruit of lips that openly profess his name. 16 And do not forget to do good and to share with others, for with such sacrafices God is pleased

John 6:53-56 (The Eucharist)
53 Jesus said to them, "Very truly I tell you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. 54 Whoever eats my flesh and drinks my blood has eternal life, and I will raise them up at the last day. 55 For my flesh is real food and my blood is real drink. 56 Whoever eats my flesh and drinks my blood remains in me, and I in them.

Who wouldn't want Christ to remain in them?

John 3:5 (Baptism)
5 Jesus answered, "Very truly I tell you, no one can enter the kingdom of God unless they are born of water and the Spirit.

To the Protestant who promotes division in faith and Protests the Catholic church, I say:

For the time will come when people will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear. They will turn their ears away from the truth and turn aside to myths. But you, keep your head in all situations, endure hardship, do the work of an evangelist, discharge all the duties of your ministry. (2 Timothy 4:3-5)
