Ro 6:6 Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.

Eph 4:22 That ye put off concerning the former conversation the old man, which is corrupt according to the deceitful lusts;

Eph 4:23 And be renewed in the spirit of your mind;

Eph 4:24 And that ye put on the new man, which after God is created in righteousness and true holiness

Col 3:8 But now ye also put off all these; anger, wrath, malice, blasphemy, filthy communication out of your mouth.

Col 3:9 Lie not one to another, seeing that ye have put off the old man with his deeds;

Col 3:10 And have put on the new man, which is renewed in knowledge after the image of him that created him:

Col 3:11 Where there is neither Greek nor Jew, circumcision nor uncircumcision, Barbarian, Scythian, bond nor free: but Christ is all, and in all.

See. all of the above shows us that the trouble is in our OLD MAN, which is first-man, Adam, or human nature.

As in Adam, all die;  so in Christ shall all be made alive.

We must crucify our old man, or first, Adamic nature, for it is the enemy of God.  If people constantly are made to look for a bad pope, some other leader, or such, to be the man of sin, or anti-Christ, then they will not see that the trouble is in ourselves and we must destroy that old way, and become new creatures in Christ Jesus.

So Adam is the man of sin, the one through whom sin entered this world,  It is in everyone, until Jesus takes it out and fills us with the Holy Nature of God, by the Holy Ghost.

Sure the popes are bad.  but then so is all sinners.  some have more power than others, but the power to send anyone to hell is only that person themselves.

Popes killed millions, but they could not take Salvation from them.  Only a disobedient heart can do that to any of us.  So, antichrist is the disobedient heart.
