When I give it all to my wife, we not only have a baby, but together we raise her, and carry her through deathly illness to health, and see her become a strong warrior for Jesus in her own right. Giving it all to each other meant we had more to give to each other and more to give to our daughter.
Giving it all to Jesus has meant having more to give. Giving that more to Mary, has mean having more to give to Jesus. And more to give, period. Giving some, in my case, to Dominic -- and lately Blessed Margaret of Castello and Blessed Jordan and Saxony have come to my attention -- ends up with a stronger passion to give all to Jesus, so that my hourly prayer to Him is that he take my heart and fill it with himself.
Sure, on PAPER, with a bean-counter spirituality, it would seem that to spend love here would mean less love to spend there. I can understand the thinking. But God is Love, so to Love there is no end. So transfinite arithmetic will do far better than the cold and parsimonious love which counts love spent here as love lost there.
This is not the zero-sum mathematics that leads to talents wrapped in a napkin and buried. This is the arithmetic of talents traded and doubled that the master who has everything will have more, and will share that more with all.
I do not see the question as a matter of spiritual mathematics but rather, a matter of Spiritual priorities.
If we love any thing or any one equal to or more than God - if only for a moment - then that thing or that one is for us an idol. And that could be a wife, a child, an idea, a church, self, possessions, etc.
Then said Jesus unto his disciples, If any [man] will come after me, let him deny himself, and take up his cross, and follow me.
For whosoever will save his life shall lose it: and whosoever will lose his life for my sake shall find it. - Matt 16:23-25
It's "about" surrendering all to God. All.
Jesus said unto him, Thou shalt love the Lord thy God with all [Greek word holos] thy heart, and with all thy soul, and with all thy mind.
This is the first and great commandment.
And the second [is] like unto it, Thou shalt love thy neighbour as thyself. On these two commandments hang all the law and the prophets. Matthew 22:35-40
This is language. And words mean something.
Rome is forever telling us ridiculous things and then furiously trying to explain away the clear and simple meaning of those words.
Men are not an "alter Christus," no matter how Rome would like to finagle the definition. There is no Christ but Jesus and He is in heaven, not on any alter.
And men are not instructed to "give their all to Mary." God forbid.
RC apologists should flee any person or organization that encourages that kind of anti-Scriptural, anti-Christian thinking. It may feel all warm and cozy and familial, but sentimental idolatry often feels good to our fallen hearts.
Resist it. Christ alone is worthy of our "all."
"For this man was counted worthy of more glory than Moses, inasmuch as he who hath builded the house hath more honour than the house." -- Hebrews 3:3
