This link is not 'Catholic' in origin.
It is a guide issued by Ealing Council, to their primary and secondary schools, advising them how they should make provision for the 25% of their pupils who are Muslim.
It indicates two main elements to me.
Firstly, that the whole educational system is becoming unacceptably skewed in favour of Islam to the degree that, adherence to these guidelines must impinge on the education of non Muslim pupils.
Secondly, the emphasis on the needs of the male Muslim pupil to the detriment of the female is unequal and has no place in the British education system.
The link copy purports to support a daily collective act of Christian worship in all state schools (how many Catholic schools observe that, I wonder).
But, in fact, it is gobbledy-gook, a fudge of words that distorts the intention and allows for an 'anything goes' approach.
"The Education Reform Act of 1988 stipulates that each state school should provide a daily act of collective worship, the majority of which are to be "wholly or mainly of a broad Christian character." These acts of worship need not only use material from the Christian tradition as long as they reflect the tradition of their beliefs".
If you are a Catholic parent please question your children's school as to their policy regarding Islam and other non Christian faiths.
And, if they don't respond correctly, write to your Bishop and copy in the Papal Nuncio.
What is taking place is not so much 'Islam creep' as 'Islam full steam ahead'.
