God's faithful people are walking steadily towards Heaven, bravely remaining true to Him, and to His laws, and united in love for Him and one another. Dissident Catholics are like people who stand at one side, saying to them, "You're going the wrong way!" - and inviting them to ignore the teachings of the Church and to resent her discipline.
The life we lead on earth must inevitably lead to either Heaven and Hell (even if to Heaven via Purgatory). Those who love Christ, and persevere in charity and purity in earthly life, will enjoy Eternal life in even greater charity and peace, with Christ. People who seethe with hatred, ambition or resentment, in this life, and persist in their selfish ambitions, will find themselves in Hell with others who are self-centered and lack love for Christ.
