According to Catholicism must we all suffer in life? In the Catholic Church there is a certain mystic aspect regarding to the suffering of Jesus Christ in which often faithful who go trough sufferings, especially for the faith, see their suffering as somehow joining to that of Christ.
Very often Matthew 16:24-26 is cited here.
Must we all suffer in life?
Sometimes people focus too much on Christ's sufferings and not how much he poured out His love on the cross. Redemption by Christ was not so much achieved by how much He suffered, but how much He loved us (CCC 616). Suffering without love has little to no value, or even be senseless. However, suffering with love for your brethren is what counts. You will be judged by how much you loved in your life (St. John of the Cross). Thus, to answer the OP's question, indeed, we all need to suffer, because nobody will enter the Kingdom of Heaven without having loved.
