Why should a single rite within one church be unable to accept priest accepted in almost all other rites?

Why should priests from the other rites not be able to serve within latin rite churches?

Why should a single rite within one church be unable to accept priest accepted in almost all other rites?

Because rites developed side by side each with its own history. It would be against charity and justice for the Latin Rite, for example, to force the Latin Liturgy on the Eastern Rites. The Divine Liturgy of St. John Chrysostom--and other Liturgies--is part of the Tradition of the Eastern Rites; Pope St. Pius V recognezed the Divine Liturgy as a valid and integral part of the Eastern Rites. Likewise, it would be contrary to charity and justice for the Eastern Rites to force a married clergy upon the Latin Rite, as celibacy has been the discipline for Latin Rite clergy for centuries now. One part of being "one church" is to recognize the differences within Rites and acknowledge the traditions within them.
