What are the links of Romanism to Islam? Are they like a brotherhood in some ways? Do they persecute christians not of the Roman faith?

Pete, I think you should be aware that Freedom of Religion under 3.9 Article 9 of the Human Rights Act 1998 won't apply in the Kingdom of God in heaven.

Religious freedom will not be tolerated in anyway, shape or form in God's kingdom; and you're not entitled to keep your faith in Reverend Moon.

You either accept me as your Saviour or I will send you to hell at the Great White Throne Judgment. (Revelation 20 v. 11-15).

Jesus said, "I AM THE WAY, THE TRUTH, AND THE LIFE; NO MAN COMETH TO THE FATHER BUT BY ME". (John 14 v. 6).

Therefore, I think you should repent before Judgment of the Nations when all false prophets will be destroyed by the Lamb: "and the devil who had deceived them was thrown into the lake of fire and sulphur where the beast and the false prophet were, and they will be tormented day and night for ever and ever." (Matthew 25 v. 31-46; Revelation 20 v. 10).

This is an ultimatum; you either accept me as your Saviour or I will send you to hell from the Judgment Seat of Christ. (John 5 v. 22-23, 5 v. 27-30; Matthew 13 v. 30, 13 v. 40, 25 v. 31-46; Revelation 20 v. 11-15).

This is not a threat, but a PROMISE.

History shows that Roman Catholics will persecute people whenever they have the power to do so.

Subjugate Satan!
