R. Tolkien, again converted to the Anglican faith . Towards the end of his life, he began to lean towards Catholicism and took the last communion according to the Catholic rite.

Clive Staples Lewis was one of the first Christian philosophers of the 20th century to put forward the bold idea of an "ecumenical Christianity" unrelated to a certain confessional affiliation. True faith has nothing to do with the differences of the various branches of Christianity, and this, according to Lewis, is the essence of "just Christianity."
