Final answer:
The assertion relating to Grace sharing the life of God reflects the Christian belief in being spiritually adopted into God's family, which is seen as true. Carolina's religious toleration policy attracting colonists is historically true, and predestination is a tenet in specific Christian denominations.
Step-by-step explanation:
The statement that Grace is sharing in the life of God in the way an adopted child shares in the life of their new family can be considered true from a Christian theological perspective, as it is analogous to the concept of Christians being adopted into God's family through faith.
Religious Concepts in Christianity
The idea of religious toleration, as mentioned in Carolina's policy, undoubtedly attracted new colonists seeking religious freedom, which is historically true.
Furthermore, the doctrine of predestination, which suggests that a person's fate is determined at birth, is a core belief in certain Christian denominations, particularly Calvinism.
Finally, the assertion that a true Christian participates in all the blessings of Christ aligns with the concept that God's grace extends to believers, negating the need for indulgence letters.
This Christian belief emphasizes the sufficiency of Christ's sacrifice and God's grace for salvation.
