Anathemas are said to condemn former Catholics to the torments of everlasting hell unless they do penance and return home to Rome. They also condemn current Catholics who do not believe every dogma of their church.

Whenever the pontiff pronounces an anathema, he uses a formula which ends with these words: "We deprive [him/her] of the Communion of the Body and Blood of Our Lord, we separate him from the society of all Christians, we exclude him from the bosom of our Holy Mother the Church in Heaven and on earth, we declare him excommunicated and anathematized and we judge him condemned to eternal fire with Satan and his angels and all the reprobate, so long as he will not burst the fetters of the demon, do penance and satisfy the Church; we deliver him to Satan to mortify his body, that his soul may be saved on the day of judgment." 

According to the Catholic Encyclopedia, when "an anathema is attached to doctrinal teaching of a general council, it is a certain sign of an infallible definition" and Catholics "are bound to believe them in order to maintain the bond of faith."

anath·e·ma     noun \ə-ˈna-thə-mə\ 
According to Merriam-Webster Dictionary:

Among the over 100 condemnations Rome issues is the one which condemns those who dare to say they have assurance of salvation. 

From Canon 16 of the Sixth Session of Trent we read:
“If anyone says that he will for certain, with an absolute and infallible certainty, have that great gift of perseverance even to the end…let him be anathema.” 

According to Jesus, we can persevere to the end: "But he who endures to the end shall be saved." Matthew 24:13 
Why would Jesus assure us of salvation and the Catholic church issue a condemnation?

Among the over 100 condemnations Rome issues is the one which condemns those who dare to say their debt is so blotted out that no punishment remains.

It is obligatory for all Catholics to accept and believe the existence of purgatory under the threat of anathema:



“If anyone says that after the reception of the grace of justification the guilt is so remitted and the debt of eternal  punishment so blotted out to every repentant sinner, that no debt of temporal  punishment remains to be discharged either in this world or in purgatory before the gates of heaven can be opened, let him be anathema” (Council of Trent, Cannon 30).

In other words... Every repentant sinner is anathema (condemned) who says “Christ has paid the full debt for my sins taking my punishment in full on the  cross and I am free from the penalty of sin”. But this is exactly what Christ came to accomplish by His death on the cross.

The Word of God no doubt teaches that  sinners deserve punishment, but…why would the Lord Jesus Himself assure His  followers that faith in Him frees them from judgment and perishing? 

"Most assuredly, I say to you, he who hears My word and believes in Him who sent Me has everlasting life, and shall not come into judgment, but has passed from death into life. (John 5:24 NKJV).

"For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life." John 3:16

Among the over 100 condemnations Rome issues is the one which condemns those who dare to say the commandments are impossible to keep.

If any one saith, that the commandments of God are, even for one that is justified and constituted in grace, impossible to keep; let him be anathema.
The Bible teaches that Christ alone kept the law perfectly. If you have sinned once you have not "kept" the commandments. To keep them would mean you never have lied, stolen, lusted, taken God's name in vain, dishonored your parents, etc. 

James 2:10 we read "For whoever shall keep the whole law, and yet stumble in one point, he is guilty of all." 
Matthew 5:17, Chris says "“Do not think that I came to destroy the Law or the Prophets. I did not come to destroy but to fulfill."

Do you honestly believe it is possible to keep all of God's commands knowing that is what Jesus accomplished on your behalf?

Dear Catholic friend, how could such condemnations be issued when the Holy Scriptures affirm them to be false?

"There is therefore now no condemnation to those who are in Christ Jesus..." Romans 8:1 NKJV
