My Aunt Grace when I was a child was a Congregationalist, she lived down the street opposite us just above us was the her church, it was really just a corrugated iron hut which she used to clean every Saturday. Occasionally I would go with her but there was picture a bit like the one above, it was Jesus surrounded by children of different nationalities, even then, I couldn't have been more that six, probably younger, it seemed a bit creepy and not very convincing, in fact I remember very consciously looking at it and deciding I rejected it and what went with it.
It was a piece of anti-evangelism, to me as a small child it was obviously fake the tin hut has long gone and the Protestant sect to which it belonged has almost disappeared. Separating the real Jesus of scripture from his Church is the best way of destroying the Church and make the Catholic Church disappear.
All the doctrines that 'Catholics' of a certain hue seem to want to disregard or are embarrassed by are actually 'of the Lord': Hell, judgement, eternal life come from Him, so do the condemnation of divorce and remarriage, the promotion of celibacy for the sake of the Kingdom. It is Jesus who speaks about these things and Christians who are so often embarrassed by them.
The teaching of the early Church, which though not explicitly taught by Jesus in the canonical Gospel is so ancient and so obviously shared by ancient Jewish communities, it was obviously teaching Jesus would have no problem with because it fits the rigour of the Gospels, it is not mentioned by him simply because no-one around him would have questioned it. I mean the prohibition on contraception and openness to life, the detestation of same sex relations, the abhorrence of abortion.
I can't help but get annoyed when people say: the Church doesn't allow divorce etc., because it is not the Church, it Jesus himself who teaches such things.
It is interesting those Christian communities who we have always judged to have validly ordained Bishops: the ancient Churches, who hold fast to authentic Christian teaching, whilst those whose orders we would say are invalid, that have itching ears and seek to bend with every wind who seemed incapable of fidelity.
