is represented as drunk with the blood of the saints, [Revelation 17:6] doubtless the supplies needful for her drunkenness are furnished by the cups of martyrdoms; and what suffering the fear of martyrdoms will entail, is in like manner shown. For among all the castaways, nay, taking precedence of them all, are the fearful. "But the fearful," says John—and then come the others—"will have their part in the lake of fire and brimstone." [Revelation 21:8] Thus fear, which, as stated in his epistle, love drives out, has punishment. (Scorpiace 9–12) Readings from the early church fathers such as these led patristic scholar David Bercot to conclude: "Since the early Christians believed that our continued faith and obedience are necessary for salvation, it naturally follows that they believed that a 'saved' person could still end up being lost [through apostasy]." Primary theological perspectives There appears to be three primary perspectives on apostasy in Protestantism: Classical or Reformed Calvinism, Moderate Calvinism, Reformed Arminianism. Classical or reformed Calvinism According to John Calvin (1509–1564), once the Holy Spirit brings a person to regeneration (i.e., gives them spiritual life) this experience cannot be lost and leads to final salvation with God. In Calvin's theology, God has predestined to regenerate some (the elect) to eternal life and not to regenerate others (the non-elect) which ensures their eternal damnation (Calvin's Institutes 3.21:5; cf. 3.2:15–40, 14.6–9, 18–20, 24.6f.). The elect may fall away from God's grace temporarily, but the truly elect will eventually be restored and not plunge into final apostasy. Calvin believed that "The Lord uses the fear of final apostasy in order to safeguard true believers against it. Only the ones who ignore the threat are in real danger of falling away." Calvin viewed the passages on apostasy found in Hebrews (6:4–6; 10:26–29) as applying to those in the church having a false faith—reprobates (i.e., unbelievers) who have never experienced regeneration. John Jefferson Davis writes: Even though Calvin believes that regeneration is irreversible . . . he does not conclude that the Christian has any cause for spiritual complacency. Persevering in God's grace requires, on the human side, "severe and arduous effort." . . . The believer needs to continually feed his soul on the preaching of the Word and to grow in faith throughout the whole course of life. Since it is easy for the believer to fall away for a time from the grace
