Is it permissible to enroll children in a nearby church to participate in its low-cost summer sports activities, especially given the husband's absence and the difficulty of transportation with five children?

It is not permissible to take children into churches for sports and activities, because it leads to corrupting their natural disposition and habituating them to objectionable things such as seeing crosses and images. This causes the child to grow up without distinguishing between a mosque and a church, and there is a fear for him of weakening faith and feeble belief.
