The white smoke is used when a new pope is selected.
Even when we have bad popes, Christ has stayed with His Church as He promised. Jesus is still with us and guiding us by the Holy Spirit.
You can either accept the teachings and the Catholic Church
based on the words of Jesus, or you can follow your own personal opinion or false teachings.
You and others may have made minor points about your position or opinion against the Catholic Church, but I haven’t seen anything of error in the teachings of the Catholic Church. Some things are mysteries, such as the Trinity and we accept this on Faith.
My hope is that eventually all will see the Truth of Jesus and follow Christ through the Catholic Church. And all that follow Jesus will join Him in Heaven.
And that the Catholic Church remains true to Jesus as One, Holy, Catholic and Apostolic Church.
