耶和华的见证人身份是一个基督教派别，他们坚信圣经是神的启示和指导。这个派别在很多方面都与其他基督教派别有所不同，其中一个重要的区别就是他们拒绝接受输血治疗。这一信仰实践的背后有如下原因:

首先，耶和华的见证人相信圣经禁止摄入或接受他人的血液。他们将对外输血视为违反上帝的教诲，并且认为接受输血等于亵渎了圣经中关于血液的圣洁性质的命令。根据《圣经·利未记》17：10-14，以及《使徒行传》15：28-29，他们相信上帝明确禁止摄取血液。

Secondly, Jehovah's Witnesses believe that there are alternative medical treatments that can be used instead of blood transfusion. They argue that modern medical advancements have made it possible to use alternative methods such as blood-volume expanders, iron supplements, and medications that stimulate red blood cell production. They believe that these alternatives are safer and more in line with their religious beliefs.

第二，耶和华的见证人相信有替代的医疗治疗方法可供选择，而不必接受输血。他们认为现代医学的进步使得使用诸如血容量扩张剂、铁补充剂和刺激红细胞生成的药物等替代方法成为可能。他们相信这些替代方法更安全，更符合他们的宗教信仰。

However, it is important to note that the refusal of blood transfusion does not mean that Jehovah's Witnesses are against medical treatment. They still seek medical help and accept other forms of treatment that do not involve blood transfusion. They value life and strive to find the most suitable medical alternatives that align with their religious beliefs.

然而，需要注意的是，拒绝输血并不意味着耶和华的见证人反对医疗治疗。他们仍然寻求医疗援助并接受其他形式的治疗，只是不涉及输血。他们珍视生命，并努力寻找与他们的宗教信仰相一致的最合适的医疗替代方法。

Furthermore, the refusal of blood transfusion is seen as a form of obedience to God's commandment. Jehovah's Witnesses believe that by adhering to this prohibition, they are demonstrating their faith and trust in God's ability to provide alternative means of healing. They believe that their decision is a personal one and should be respected, even if it may seem unconventional to others.

此外，拒绝输血被视为对上帝诫命的一种服从。耶和华的见证人相信通过遵守这一禁令，他们展示了对上帝提供替代治愈方式的信仰和信任。他们认为这是一个个人的决定，并且应该受到尊重，即使在他人看来可能不寻常。

In conclusion, Jehovah's Witnesses' refusal of blood transfusion is deeply rooted in their religious beliefs and interpretation of the Bible. They believe that accepting blood from others goes against God's commandment and prefer to explore alternative medical treatments. While this may seem controversial to some, it is important to respect their personal choices and beliefs.

总之，耶和华的见证人拒绝输血源于他们的宗教信仰和对圣经的解读。他们相信接受他人的血液违反了上帝的诫命，更倾向于探索替代的医疗治疗方法。虽然这可能在某些人看来有争议，但尊重他们的个人选择和信仰是非常重要的。
