Who said that Jesus isn't sufficient? Spin the scripture all you want but do not impute to us the theologies we don't have.
Paul: "If God is for us, who can be against us? He who did not spare his own Son, but gave him up for us allhow will he not also, along with him, graciously give us all things? Who will bring any charge against those whom God has chosen? It is God who justifies. Who is he that condemns? Christ Jesus, who diedmore than that, who was raised to lifeis at the right hand of God and is also interceding for us. Who shall separate us from the love of Christ?"
Peter: "In his great mercy he has given us new birth into a living hope through the resurrection of Jesus Christ from the dead, and into an inheritance that can never perish, spoil or fadekept in heaven for you, who through faith are shielded by God's power until the coming of the salvation that is ready to be revealed in the last time."
John: "But if anybody does sin, we have one who speaks to the Father in our defenseJesus Christ, the Righteous One. He is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world."
The Catholic Church: "Purgatory (Lat., "purgare", to make clean, to purify) in accordance with Catholic teaching is a place or condition of temporal punishment for those who, departing this life in God's grace, are, not entirely free from venial faults, or have not fully paid the satisfaction due to their transgressions."
