I find this interesting; many non-Catholic, Protestant Christians who might generally be in disagreement with / antagonistic towards / openly hostile towards aspects of Orthodox-Catholic theology or praxis nonetheless have a deep admiration for Saints like Francis of Assisi, Teresa of Calcutta, Catherine of Sienna, Polycarp, Teresa of Lisieux, or Seraphim of Sarov. Notwithstanding that it is awesome and good that Protestant Christians recognize the holiness, purity, example, and image of Christ in these Saints and are inspired by them, it is also noteworthy that none of the people mentioned above were Protestants, and in life they taught and affirmed much that Protestantism would not be able to reconcile or agree with, as an essential part of their lives in Christ.
That, too, is something to take into consideration, especially for non-Catholic / Orthodox Christians seeking to live holy, obedient, luminous and Godly lives. How is it that Orthodoxy and Catholicism produces Saints like these?
