Let us trustingly invoke Most Holy Mary that she may guide our hearts always to draw from the well of divine mercy, which liberates and heals our human condition, filling it with all grace and benevolence, with the power of love.Notice the problems.
1) Rather placing our trust in God alone, Ratzinger wants us to trust Mary.
2) Rather than ascribing the highest degree of holiness to God alone, Ratzinger calls Mary "Most Holy"
3) Rather than ascribing guidance of our hearts to the Holy Spirit, Ratzinger ascribes it to Mary.
I suppose we should, on some level, be thankful that the remainder of the sentence relates to divine mercy and its consequences. It's small conciliation, however.
Moreover, also notice the synergism of the description - the object of the trust and invocation is not simply to receive grace from God, but rather to receive Marian guidance for us to use our own abilities to "draw from the well."
By contrast, Jesus says:
John 4:14 But whosoever drinketh of the water that I shall give him shall never thirst; but the water that I shall give him shall be in him a well of water springing up into everlasting life.
The gifts that the Father gives us, promised to us by Jesus, are greater than those promised by the leader of the Roman communion and sought by those in communion with him. Whereas they have to draw from a well, our well springs up to us.
We also have a better mediator to invoke than Mary. Our mediator encouraged us in this way:
John 4:10 Jesus answered and said unto her, If thou knewest the gift of God, and who it is that saith to thee, Give me to drink; thou wouldest have asked of him, and he would have given thee living water.
You see, we don't have to just ask Jesus for guidance to the divine well - if we ask water of him, he will give it to us!
Dear readers, drink from the rock! Not from Peter the apostle but Jesus Christ the Righteous. As it is written:
1 Corinthians 10:4 And did all drink the same spiritual drink: for they drank of that spiritual Rock that followed them: and that Rock was Christ.
