Christian traditions contradict YHWH & Jesus almost by default.
Concerning becoming a Eunuch, or Castration:
[The Council of Nicaea decided what Christians were going to believe about God. After the council these beliefs were enforced by the sword.
Matthew 11:12 KJV And from the days of John the Baptist until now the kingdom of heaven suffereth violence, and the violent take it by force.]
Council of Nicaea: "But if anyone in good health has castrated himself, if he is enrolled among the clergy he should be suspended, and in future no such man should be promoted."
Isaiah 56:4-5 KJV
4 For thus saith the LORD unto the eunuchs that keep my sabbaths, and choose the things that please me, and take hold of my covenant;
5 Even unto them will I give in mine house and within my walls a place and a name better than of sons and of daughters: I will give them an everlasting name, that shall not be cut off.
Matthew 19:12 KJV - For there are some eunuchs, which were so born from their mother's womb: and there are some eunuchs, which were made eunuchs of men: and there be eunuchs, which have made themselves eunuchs for the kingdom of heaven's sake. He that is able to receive it, let him receive it.
