She collected dying people off the streets and gave them a place to die. There's probably no way of knowing if she or her helpers, actually told these souls the Gospel, ie of Jesus, before they died, or even if they were in a position to hear it. She wanted "love" to save them. Her "love" didnt do much for them physically and certainly not spiritually. It appears she used them as the vehicle to "preach" to the Hindus.
Mother Theresa, like all Catholics, preached that the way to Jesus was through "the blessed Virgin Mary". Like I noted earlier, even at the first of Genesis, in the Cain and Abel story, God said that the way to worship Him was through the blood of the lamb (Jesus), yet Cain insisted he had a better way.
Theresa also said this:
We never try to convert to Christianity those who receive our help, but in our work we bear witness to the love of Gods presence and if Catholics, Protestants, Buddhists, or agnostics become for this better men-simply better-we will be satisfied. (Life in the Spirit: Reflections, Meditations and Prayers, pp. 81-82) If in coming face to face with God we accept Him in our lives, then we are converting. We become a better Hindu, a better Muslim, a better Catholic, a better whatever we are
.What God is in your mind you must accept. (Mother Teresa: Her People and Her Work, p. 156)
I some of her writings she doubted her salvation, she substituted works for the gospel
My heart breaks for her.. my hope is that someone presented the gospel to her before she died..
We become a better Hindu, a better Muslim, a better Catholic, a better whatever we are .What God is in your mind you must accept. (Mother Teresa: Her People and Her Work, p. 156)
Which is consistent to the universalist nature of Roman Catholicism. Just a casual reading of the RC Catechism will show that Heaven's gate is swung wide open to most, if not all religions.
