245 On numerous occasions, I have spoken of “a principle indispensable to the building of friendship in society: namely, that unity is greater than conflict… This is not to opt for a kind of syncretism, or for the absorption of one into the other, but rather for a resolution which takes place on a higher plane and preserves what is valid and useful on both sides”. All of us know that “when we, as individuals and communities, learn to look beyond ourselves and our particular interests, then understanding and mutual commitment bear fruit… in a setting where conflicts, tensions and even groups once considered inimical can attain a multifaceted unity that gives rise to new life”.
