Christianity teaches that all life is a precious ❌ from God. Another way of saying this is to call life sanctified, ❌ and/or sacred (i.e. human life is associated with the ❌/God). Every person is of ❌ worth to God, although a person may do something which is ❌ or worse than another person. It is also Christian belief that a human's ❌, health or ability does not make the person more or less ❌; this is why the concept of the ❌ of life is so important in considering ❌ ethics.
The sanctity of life means that we should be treated with ❌ as an act of worship to God. Any ❌ of the human body, for example through the use of illegal drugs, goes completely against this religious teaching an is ❌ to believers. Christians believe that each person should ❌ God through their bodies and in the way that they live their ❌, and that God not only gives life but he ❌ it and guides people in each situation they are in, if they have ❌ in him.

The Doctrine of ❌ Effect suggests that if doing something ❌ good has a morally bad side-effect, it is ❌ okay to do it providing the bad side-effect was not ❌. This is true even if you foresaw that the bad ❌ would ❌ happen.

Catholics are firmly ❌ to any form of therapeutic cloning that uses stem cells harvested from an ❌. This is because Catholics believe that life begins at ❌ and so harvesting stem cells from an embryo is equivalent to an act of ❌ and an insult to the sanctity of human life. "To create embryos with the intention of ❌ them, even with the intention of helping the sick, is completely incompatible with human ❌." However, Catholics have no issue with, and support, any form of ❌ cloning that doesn't harm the source of any stem cells used.
On this issue, Anglicans are not as strict as Catholics, being ❌ of therapeutic cloning that uses stem cells harvested from embryos when it is for the treatment of a '❌ condition', 'absolutely ❌' and 'once all other avenues have been explored'. This ❌ may have been justified by the Anglican teaching that an embryo doesn't have a right to life until it is ❌ days old and Jesus' teachings on love and ❌ ('Love thy neighbour as ❌' - Mark 12:❌).
