Another one, may suggest Abdallah that you read some of the previous posts which will provide you the answer.
May I also suggest that you look at Scripture not rubbish that moves under a Christian name. I guess most people in here do not even consider the Catholic church as Christian; as you mention, most or many of the priests hardly have any faith. That of course is not to say that there are no true Christians within the Catholic church.
However, rather than concentrating on groups or individuals who despite of religious title deviate from the Christian Scripture, how about looking at Christian Scripture and consider true Christianity, in which neither rape, pedofila or imorality is accepted. Because none of those cases you mentioned represent the Christian faith. A true Christian is recognised by his life and conduct; in fact the Bible clearly states that on the day of Judgement, many people who possessed the title Christian will go to hell, because their faith was not genuine.
If you want to attack the Christian faith, then attack the moral of the New Testament, the Gospel and the Epistles, otherwise you are merely waisting your time.
Let me however, point out that the imorality which you so correctly condemns is both encouraged, and permissible in the Religion of Islam.
I have posted this before and now I will do it again:
Rape of female slaves
Sura 70:22-30; 23:5-6; 4:24 give full permission for the Muslims to rape their female slaves (the girls taken in war). In Sura 33:50 a special permission is given for Muhammed.
"...who restrain their carnal desires (except with their wives and slave girls, for these are lawful to them..." (Sura 23: 5-6)
"And all married women are forbidden unto you save those captives whom your right hand possess. It is a decree of Allah for you (Sura 4: 24).
According to Tabari vol.39, p.194 the ruler of Alexandria gave a young Christian girl as a gift to Muhammad, her name was Mariyam. Muhammad never married her but used to sleep with her, and she even gave birth to a son who died after 18 months..
According to Sahih Bukhari vol.5#637 Ali had sex with a slave girl whom he saw and found beautiful, and Muhammad seemed to have no objections.
Narrated Buraida: The prophet sent Ali to Khalid to bring the Khumus (part of the war booty) and I hated Ali, and Ali had taken a bath (after a sexual act with a slave girl from the Khumus). I said to Khalid, "Don't you see this (i.e. Ali)? When we reached the prophet I mentioned that to him. He said, "O Buraida! Do you hate Ali?" I said, "Yes." He said, "Do you hate him for he deserves more than that from the Khumus." (Sahih Bukhari, vol.5, #637)
Rape of female captives
According to Sahih Bukhari vol.9#506; Sahih Muslim vol.2#3371 Muhammad’s followers used to come to Muhammad after battles, to seek permission and advise to engage in sexual activity with the girls taken in battle. They doubted for several reasons, however, permission was granted.
At one point Muhammad gave them permission and told them that it is up to Allah who gets created anyway, thus permission was given.
a. The permission from the Koran
"Prophet, We have made lawful to you the wives whom you have granted dowries and the slave girls whom God has given you as booty;..." (Sura 33: 50)
b. Doubt due to fear of less money for selling pregnant slaves
Narrated Abu Said Al-Khudri that while he was sitting with Allah's messenger we said, "Oh Allah's messenger, we got female captives as our booty, and we are interested in their prices, what is your opinion about coitus interruptus?" The prophet said, "Do you really do that? It is better for you not to do it. No soul that which Allah has destined to exist, but will surely come into existence." (Sahih Bukhari, vol.3, # 432) (further reference Bukhari Vol. 3, #718)
c. Fear due to pregnancy
Narrated Abu Said Al-Khudri that during the battle with Bani Al-Mustaliq they (Muslims) captured some females and intended to have sexual relations with them without impregnating them. So they asked the prophet about coitus interruptus. The prophet said, "It is better that you should not do it, for Allah has written whom He is going to create till the Day of Resurrection". (Sahih Bukhari, vol.9, #506) (further reference Bukhari 5: 459)
d. Lust or ransom?
Abu Sirma said to Abu Said al Khudri: "O Abu Said, did you hear Allah's messenger mentioning about al-azl (coitus interrupts)?" He said, "Yes", and added: "We went out with Allah's messenger on the expedition to the Mustaliq and took captive some excellent Arab women; and we desired them for we were suffering from the absence of our wives, (but at the same time) we also desired ransom for them. So we decided to have sexual intercourse with them but by observing azl" (withdrawing the male sexual organ before emission of semen to avoid conception). But we said: "We are doing an act whereas Allah's messenger is amongst us; why not ask him?" So we asked Allah's messenger and he said: "It does not matter if you do not do it, for every soul that is to be born up to the Day of Resurrection will be born". (Sahih Muslim vol.2, # 3371)
e. Doubt since their men are polytheists
Abu Said al-Khudri reported that at the Battle of Hunain Allah's messenger sent an army to Autas and encountered the enemy and fought with them. Having overcome them and taken them captives, the Companions of Allah's messenger seemed to refrain from having intercourse with captive women because of their husbands being polytheists. Then Allah, Most High, sent down regarding that: "And women already married, except those whom your right hands possess (Quran - 4:24), (i.e. they were lawful for them when their Idda (menstrual) period came to and end). (Sahih Muslim, vol.2, #3432)
f. Doubt since their husbands watch them being raped
Abu Said al-Khudri said: "The apostle of Allah sent a military expedition to Awtas on the occasion of the battle of Hunain. They met their enemy and fought with them. They defeated them and took them captives. Some of the Companions of the apostle of Allah were reluctant to have intercourse with the female captives in the presence of their husbands who were unbelievers. So Allah, the Exalted, sent down the Quranic verse, "And all married women (are forbidden) unto your save those (captives) whom your right hand possesses". That is to say, they are lawful for them when they complete their waiting period."" [The Quran verse is 4:24]. (Sunan of Abu Dawud, vol.2, #2150)
Muhammad and Child brides
It is recorded in the Hadiths that Muhammad’s second wife (Aisha) was not less than six years old when he (Muhammad) took her into marriage. The first sexual intercourse took place when Aisha was nine years of age; we are told that Muhammad was fifty-six years of age.
Bukhari vol. 7, #65: "Narrated Aisha that the prophet wrote the marriage contract with her when she was six years old and he consummated his marriage when she was nine years old. Hisham said: "I have been informed that Aisha remained with the prophet for nine years (i.e. till his death).""
Bukhari vol. 7, #88: "Narrated Urwa: "The prophet wrote the (marriage contract) with Aisha while she was six years old and consummated his marriage with her while she was nine years old and she remained with him for nine years (i.e. till his death).""
From Abu Dawud, Vol. 2, #2116: "Aisha said, "The Apostle of Allah married me when I was seven years old." (The narrator Sulaiman said: "Or six years."). "He had intercourse with me when I was 9 years old."
Temporary marriages
Shih Al-Bukhari part 7 page 37: While we were in the army, Allah's Apostle came to us and said, you have been allowed to have pleasure (Muta) so do it. If a man and a woman agree to marry temporarily, their marriage should last for three nights, and if they want to continue, they may do so.
There is also a very famous story related to us by Ibn Mas'ud and recorded in all the Islamic sources:
We used to participate in holy battles led by Allah's Apostle and we had no wives with us. At that time, he allowed us to marry women with a temporary contract and recited to us this verse from the Quran: 5:87: Oh you who believe, make not unlawful the good things which Allah (God) has made lawful for you.
This was usually done by seducing a tribe women with clothes or money and Muhammad made a great effort in legalizing and even bringing these women to the camp (Sahih Moslem, vol.3, p.553-556). The practice was however only allowed when it was necessary (as the Muslims put) even after Muhammad’s death (Ibn Qayyim al-Jawziyya, part 3, p.459).
There is however, debate amongst Muslims scholars today, whether temporary marriages (muta) is still permissible.
So here we have it all terrorism, slavery, rape, pedofila, prostitution; well Abdallah if you can find anything similar within the New Testament text, you have made your day--at that is the challege I will give you.
Be blessed
