Church officials have admitted that some bishops in the UK may be failing to follow the Church's own child protection guidelines.
Since 1994, the Catholic Church has had strict child protection procedures.
These state that in any case where a complaint is made against a priest, social services should be informed and the priest removed from parish duties.
An investigation for Radio 5 Live found one priest under investigation who was still working.
Another, recently suspended, was allowed to work in a primary school while under suspicion of abusing children.
He had been accused of abuse twice before.
Several complaints
Since 1996, six priests have been convicted of child abuse.
In each case, the church knew of previous allegations.
The Church introduced the guidelines following the case of a Midlands priest jailed for sexually abusing seven children.
Numerous complaints had been made against him, but the Church failed to call in the authorities.
Nine offences
The Catholic Church in England and Wales says it it is fully committed to child protection, but said there may be individual cases where the guidelines are not being followed.
One priest, Father Michael Hill, was jailed two years ago after admitting nine counts of of indecent assault and one of gross indecency.
The mother of one of the children he abused said he should have been stopped.
She said he should have been barred from working in any parish and given help, rather than allowed to continue working as a priest.
