It has become less acceptable in society to be religionist, that is, to believe those of a particular religion are more pleasing to God - in just the same way that racist attitudes are no longer acceptable.
Society has become less tribal and caretakers of religious doctrine like the Pope have to adopt attitudes that reflect this new reality if their religion is to thrive.
The problem is that many religious texts crystallised out when tribalism was the norm.
The Bible is anti-Semitic in parts and negative about Pagans too. Eternal life, according to the Bible, is reserved for those who recognise Jesus as their divine saviour. In parts of the Quran there is a negative view of outsiders too. For example, somewhat ironically, it is said that Trinitarians - those who believe in the divinity of Jesus - are destined for hell. In other words, the belief that will get you into heaven according to Christianity is the very same belief that will guarantee you’re heading for hell in Islam!
Many modern-day Christians and Muslims are uncomfortable with the tribalism/religionism in their holy books. As a consequence there is a dichotomy between the beliefs found in ancient scripture and the views expressed by those who claim to be adherents.
One of the reasons the Sikh religion came into being was because there was a need for a spiritual system that encouraged religious tribes to live side by side in harmony. Sikhs don’t believe in evangelism. There is no need for it because they believe in an equal opportunities afterlife. In their view God doesn’t discriminate amongst people holding different beliefs. They are completely accepting of the older faiths of Christianity and Islam.
It seems to me that there is less tension between Sikhism and modern mores than is the case for Christianity and Islam.
