Actually none of it is based on that at all.
The reasons that the Catholic Church originally opposed it was due to Masonic belief/ practices. Cremation was seen as a denial of the Bodily Resurrection which the Catholic Church has always taught will occur at the end of time.
You see this belief in the Apostles creed: I believe in the Holy Spirit, the Holy Catholic Church, the communion of saints, the forgiveness of sins, the resurrection of the body, and life everlasting. Amen.
As well as the Nicene Creed:We look for the resurrection of the dead, and the life of the world to come. Amen.
Cool - so it’s not based on Biblical passages but creeds written several centuries after Jesus’ time. And nothing about the Church owning the only “approved” places for burial for hundreds of years...
A real bummer for all the Christians that have been mangled, burned up, blown apart, lost limbs, etc.
