Purgatory is an eschatological reality that occurs at the end of this earthly life. Regardless of the fact that the notion of purgatory as such is not directly indicated within the Holy Scripture, it is one of the essential components of the teaching of the Catholic Church. In presenting the mentioned doctrine we can use general settings about purgatory, biblical texts as well as church tradition and councils. Purification is reflected in the suffering of the soul, but it takes place in Gods love which in this way wants to prepare that soul for the wedding feast of the Lamb. The Catechism of the Catholic Church addressed the subject of purgatory within paragraphs 1030, 1031 and 1472. Some similarities with the catholic doctrine of purgatory can be found in protestants, orthodox and teaching of reincarnation. The testimonies of the saints are a vivid depiction of the image of purgatory. The biblical verses of the Old and New Testament are indirectly supporting the existence of purgatory. Church teachers and councils have dealt in detail with this topic over the centuries.
